About APIC

(Advance Photonic Integrated Circuits)

Established in 1999, APIC Corporation is both a research and development center as well as a manufacturer of commercial lasers, photodetectors and silicon photonic circuits. APIC’s core business and patented IP is in compound semiconductor and silicon photonic research, device design, and wafer fabrication. APIC manufacturing spans vertically from individual devices up through integrated rack-mounted transmitters and receivers.

Technology Focus

APIC operates two closely coordinated business areas:


Radio frequency over fiber is for technology development and system integration of products related to the transmission of analog, and highly modulated digital signals over single-mode fiber. The application space includes Fiber to the X (FTTx), passive optical networks (PONs), distributed antenna systems (DAS), spectrometry and electronic warfare.


High Performance Computing is for technology development and system integration of optical circuits in silicon integrated with CMOS devices to achieve ultra efficient links and networks for high performance computing. The application space includes high bandwidth density, energy efficient photonic interposers for heterogeneous processor integration and optical links. The operation of optical nodes at temperatures of 4 degrees Kelvin support high bandwidth communication between processors at room temperature with processors or sensors operating at extreme cold temperatures such as for quantum computing.

Our Staff

Birendra (Raj) Dutt, PhD


Dr. Dutt founded APIC Corporation with the goal of inventing pioneering technology in the photonics industry. This has encompassed work in the areas of microelectronics, photonics, and optoelectronic integration. Products include highly integrated photonic circuits that incorporate a variety of functional components through use of silicon-on-insulator technology. Dr. Dutt has developed and holds several significant patents in the fields of radar, applied physics, and photonics. He graduated with honors from the Indian Institute of Technology in 1971. Dr. Dutt earned a master’s degree from Virginia Polytechnic Institute and State University. He later studied the nonlinear physics of solitons at the University of Southern California (USC) and earned a doctorate in experimental fluid mechanics from USC, with part of his thesis work undertaken at the Jet Propulsion Laboratory, California Institute of Technology.

James Chan, PhD

Vice President of Radar Systems

Dr. Chan is a cofounder of APIC and assumed his role as senior scientist in 2003. In this capacity, he pioneered APIC's work in the area of SOI-based technology as well as in the integration of photonic and electronic components on an SOI substrate. He has more than 28 years of industrial experience at the helm of government-contracted research-and-development efforts. Dr. Chan holds several patents and hasauthored a number of external publications and proprietary reports. He received his bachelor’s degree from California State University at Chico and both his master’s degree and his doctorate in electrical engineering from the University of California at Los Angeles.

Koichi Sayano, PhD

Vice President of Optical Systems

Dr. Sayano has more than 20 years of experience in technical research and development, and in management. Before joining APIC, he served as Director of Research at Research & Development Laboratories, where his responsibilities included the system integration and testing of an optical code-division multiple-access (OCDMA) fiber-optic communication system as well as the testing and evaluation of erbium-doped optical sources and fiber amplifiers, photonic integrated circuit chips, and other optical components. He received his bachelor's degree, master's degree, and doctorate in applied physics from the California Institute of Technology.

Denise Lortie

Vice President of Administration

As a co-founder of APIC Corporation in a role as its VP of Administration and Corporate Secretary to the Board of Directors, her career started in the Government and Defense industry such as R&D Associates and Science Applications, Inc. She has over 30 years' experience in various aspects of administration, contracts and management and is responsible for the implementation of corporate policy. She also operates as a liaison to support U.S. national security interests and international companies' legal compliance.

Bob Walter

Vice President, Operations

Mr. Walter has over 27 years of program management experience in projects ranging from M1 Abrams Tank fielding, to research and development at the Defense Advanced Research Projects Agency (DARPA). Mr. Walter is a DAWIA Certified U.S. Department of Defense acquisition professional and a retired Army Lieutenant Colonel with 20 years of experience in combat arms and Army Acquisition. As a DoD contractor for 14 years, he provided technical and managerial support for program formulation, planning, solicitation, and execution on numerous projects in DARPA and other DoD agencies. Mr. Walter earned his BS in EE from the United States Military Academy at West Point in 1981 and an MSE studying robotics at the University of Texas in Austin in 1992.

Ashok K. Kapoor

Vice President Silicon Photonics and HPC

Ashok K. Kapoor received the B.Tech. degree in electrical engineering from the Indian Institute of Technology (IIT), Kanpur, India, in 1973, and the M.S. and Ph.D. degrees from the University of Cincinnati, Cincinnati, OH, in 1979 and 1981, respectively. He started his career working for the Fairchild Research Center, Palo Alto, CA, as a Member of the Research Staff. Later, he worked for Hewlett Packard integrated circuit research group, at LSI LOGIC where he managed the Device Technology Group which included device modeling, TCAD, and device reliability and also managed the testing laboratory and at National Semiconductor Corp as the Director of Research. Since 2001, he has cofounded multiple startups, including Sensitron to develop systems based on wireless networked sensor, SemiSolutions which worked on leakage reduction in nano-scale MOS transistors and in, 2005, he cofounded DSM Solutions to develop complementary JFET technology for low-power VLSI, and worked as the Chief Technology Officer. In 2011, he joined APIC/Photonic Corp to head the Silicon Valley Operations, working on integration of photonic with CMOS as the founder of the Silicon Valley Operations of the company. Also, he manages the technical collaboration with Universities for the company. He was deeply involved with the research consortium SRC in various capacities during early 1990s, as a Member of the Executive Technical Advisory Board from 1992to 1996. In 1995, he was elected as the CoChair of the Executive Technical Advisor Board of the SRC where he helped set direction of the research funding . He was also a Member of the SIA Roadmap Committee from its initiation until 1997. He has coauthored over 30 publications and is listed as an inventor or co-inventor of over 100 U.S. patents. He was the recipient of the Inventor of the Year Award from LSI Logic in 1995. Dr. Kapoor is a member of the IEEE Electron Devices Society, photonic society, Optical Society of America, Material Research Society, and Sigma Xi. His current research is centered on high performance silicon photonics.
