Silicon Based Integrated Photonic Circuits: A Paradigm shift of Fiber Optical Technology Toward Low Cost Optical Communication Systems

 Chi Wu

Founder of LightCross Inc.

(626) 255-5857

ABSTRACT

 Data traffic, with the growth rate of 90% per year, has exceeded the voice traffic in year 2001, which has a growth rate of 10% per year. However, the capital cost and operating cost for transmitting data traffic rise much quicker than its revenue and profit. This is one of the major challenges for carriers.

          Integrated photonic circuits, just like Moors Law, are about getting more for less. It offers more functionality, better performance, and better reliability, for the smaller size, lower power consumption, lower cost and simple logistics.  It addresses exactly the most critical need for the reduction of network capital and operating cost.

In this presentation, different materials of fabricating integrated photonic circuits will be compared. The challenge, advantages, and future perspectives of Silicon based integrated optical circuits will be discussed. It concludes that silicon based Integrated optical circuits riding on the back of the success of silicon IC technology, which is now being commercially implemented in 12 inch wafers, will provide future solution for the lowest cost and large volume optical components for optical communication systems.

Chaotic Optical Communication with Chaotic Pulsing Semiconductor Lasers

 Shuo Tang and Jia-ming Liu

UCLA

Abstract

 Chaotic optical communication is of great interests recently because of potential applications in secure communications and spread spectrum communications. Chaotic communication is a communication scheme that uses chaotic waveform as carrier to transmit messages. In a chaotic communication system, a chaos generator is used to generate the chaotic waveform. Chaotic waveform has the characteristics of noise-like time series and broadband spectrum, which are characteristics desired for hiding messages in both time and frequency domains. Messages are encoded onto and hidden within the chaotic waveform and further transmitted to a receiver through a communication channel. At the receiver, an identical chaos generator is used to duplicate the chaotic waveform. Message decoding is achieved through subtracting the chaotic waveform from the received signal.

Chaotic dynamics exists in many nonlinear systems. The chaotic waveform in our experiment is generated by a semiconductor laser system with delayed optoelectronic feedback. The feedback delay time, feedback strength, and DC bias current of the semiconductor laser are adjustable operating parameters. The laser system generates fast chaotic pulse stream under certain operating conditions through a route of quasi-periodicity, in which the laser dynamics develops from CW, to regular pulsing, to quasi-periodic pulsing, and finally to chaotic pulsing. The chaotic pulse stream has noise-like fluctuation in both pulse intensity and pulse interval on a sub-nanosecond time scale. The chaotic pulse stream is used to encode and decode high-speed digital messages for chaotic optical communications.

Our chaotic optical communication system is composed of two chaotic pulsing semiconductor lasers that serve as transmitter and receiver respectively. The two lasers are coupled together through a communication channel. To ensure reliable message recovery, the output of the receiver laser needs to synchronize with the chaotic pulsing waveform from the transmitter laser. The transmitter and receiver lasers are carefully chosen identical lasers and their operating conditions are fine-tuned for parameter match that is very crucial in chaotic communications. In the experiment, high quality of chaotic synchronization is achieved between the transmitter and the receiver lasers. The receiver laser nicely reproduces the chaotic waveform from the transmitter laser. In the chaotic optical communication experiment, digital messages are encoded onto the chaotic pulsing carrier through additive chaos modulation. At the receiver, the chaotic pulse waveform is subtracted from the received signal for decoding. Message encoding and decoding of pseudo-random NRZ signals at 2.5 Gbit/s bit-rate is demonstrated and good quality of message recovery is achieved. This is the first demonstration of 2.5 Gbit/s chaotic communication experiment. The success of this experiment shows that chaotic optical communication is applicable at high bit rate that matches with commercial optical communication standards.

Cooperative-Create a new era in Chinese Photonics World

Dr. Peter T. C. Shih

Professor, Taiwan University, ROC

Abstract

     Following last year's speech, Dr. Shih elaborates more on the subject of Optoelectronics in China, Taiwan and Chinese in North America.  With the cooperative scheme in mind: cultivate and combine the value chain of the human resource, market, innovation, dynamic, finance, the strength of the tri-party.  Together we can create a new era of Photonic world and eventually a Chinese Photonic World.

  Biography

            The optoelectronic industry in Taiwan is seen as a new avenue of growth today when the development of Taiwan's Industry has reached turning point to move into higher-value-added industry.  Dr. Peter T. C. Shih is among the first to recognize that optoelectronics is the key technology for developing Taiwan's high-tech industry and economy.

            Dr. Shih was invited to be a technological consultant for Taiwan, Republic of China in 1982, after years of service at Rockwell SRL in the U. S. A.  Owing to his suggestion, optoelectronics was approved by the government to be included as one of the major thrust area in science and technology development policy of the government.  In 1984, Executive Yuan, Republic of China, appointed Dr. Shih as the executive director of Electro-optics Science & Technology Committee, National Science Council (EOC).  During his tenure, he made accomplishments to the EOC's missions.   He coordinated six departments to implement the 8 years program of Electro-optic Technology and Industry Development (1986-1994) with the total budget of NT$10 billion, and additional 4 years program. (1996 – 1999).   The program also created two organizations, ITRI's Optoelectronic Institute and PIDA, which geared up the development of optoelectronic industry in Taiwan. 

            In addition, Dr. Shih showed his insights into the cooperation among industry, government, and academy.  He is the first person who proposed on the cooperation between industry and academy to the National Science Council.  As a result, four optoelectronic programs of the cooperation were implemented successfully.  Two of the programs achieved world record.  Furthermore, he initiated the International Electro-Optic Exposition held every other year since 1987.  The exposition brought great interaction between industry and academy for optoelectronic technology, product, and international image.  In 1993, Photonics Industry and Technology Development Association (PIDA) was founded, under the effort of Dr. Shih, by the funding and donation of government and industry.

            The other contribution from Dr. Shih is the promotion for the optoelectronic industry.  He helped and led the traditional industry such as cement, textile, steel, paper, cable, etc. to re-direct their investment to optoelectronics and inspired overseas experts to invest optoelectronic product in Taiwan.  He also developed international cooperation.  For example, he signed agreements with Japan's OITDA for information sharing, staff visiting, report translation; co-sponsored conference with SPIE and held 4 nations Opto’s meeting.   Besides this, he helped form the Photonics Society of Chinese - Americans (PSC) in North America for overseas Chinese and he also helped promote the relationship between France and Taiwan in different sectors.  Dr. Shih's foresight in the importance of mass media and communication channel for promotion of optoelectronics enable him to take charge of publications successfully; for example, the Opto News magazine is well received and circulated among Chinese readers around the globe.  To date, Taiwan’s opto industry has reached a production value total 11 billion US dollars, products such as LED, LCD, CD-R, CD-ROM, scanner emerge as number one producer in the world.  Last year’s investment is a record high 6 billion US dollars.

            Dr. Shih's passion for the optoelectronics drives him to devote himself to develop optoelectronics for Taiwan.  Meanwhile, Dr. Shih points out the "ecological society" will be the new direction for human's endeavor after the "information society".  Therefore, he think that the next phase of work is again to promote optoelectronics & laser applied in ecology, environment protection, energy, bio-medicine, agriculture, and ocean for the sustainable resources and improving human's life quality for the coming 21st century.

     Dr. Shih studied his Ph.D. in France, Grenoble in the 70’s, he was born in August 5 1949.  He is presently with the National Science Council, head of the Electro-optics Committee and also the adjunct professor at the National Taiwan University, Taipei, Taiwan.  He has received numerous awards, honors from different societies, agencies & countries including UK, USA, Singapore & Japan.

A VC's Perspective on Photonics Investment

 Ron Cao
 Investment Manager, KLM Capital Group

 Abstract

Both 2000 and 2001 were very difficult years for venture investments.  For venture capitalists, those two years were the worst years ever on record in terms of returns. According to Venture Economics, the average median net IRR to LPs for vintage year funds between 1981 and 1998 were over 20%, whiles the 1999 and 2000 vintage year funds have significantly under-performed with negative double-digits returns so far. These numbers will get worst as more startups file for bankruptcy and fund manager continue to re-value their portfolios.

At the heart of the telecom meltdown lies fiber optics. VCs poured a record amount of dollars into photonics from 1999 to 2001.  Some of the early investments paid off, while most VCs are scrambling today to find any liquidity for their portfolio. As the photonics market continue to stabilize and consolidate, a couple of things are clear.

1) The first generation of technology is relative mature

2) Market is small. The most dominant player in this market, JDSU, only generated 286M in revenue this last quarter.

Currently, VCs are spending most of their time/money "rescuing" their current portfolio companies.  Most of the new deals closed today are second and third round opportunities at first round prices.  Only a few first round deals are being done, because of funding risk and lack of visibility to revenue.  VCs are going to school to learn the basics.  Business plans with incremental technology are simply not going to be funded. Technology itself is not enough. Revenue, cost and road to profitability are pretty important things too.  Experienced management team is a must.  Valuations will continue to be low/or/back to "normal".

Going forward, many VCs will all-together stop investing in fiber optics.   Other VCs who might have longer horizon or more balanced portfolios will continue to look for innovations in this space.  Unlike the .com bubble, technology innovation will continue to generate value in photonics.  Some of the interesting areas of development include planar integration, low cost amplifiers, reconfigurable/tunable devices, and high-speed electronics. For entrepreneurs who truly have something unique, this is absolutely the perfect time to start your business. Large companies are forced to focus on short-term revenue. As they cut down their R&D efforts, this is the perfect opportunity for startups to charge ahead.  Find patient investors with experience and knowledge in your space and start your business today!
