Dr.
Suwat Thaniyavarn (Founder, President, and CEO)
Prior to forming EOSPACE Inc., Dr.
Thaniyavarn headed the Integrated Optics/Microwave Photonics Group at the
Boeing High Tech Center. In late 1997, Dr. Thaniyavarn formed EOSPACE
Inc., spinning integrated optics technology out of Boeing. All of the
key members in his group joined the company in 1998.
Dr. Thaniyavarn has been working for nearly
20 years on LiNbO3 optical integrated circuit (IC) technology for aerospace
applications, starting in 1982 at the TRW Electro-Optics Research Ctr., and
later at the Boeing High Tech Ctr. He started with early work on
domain inversion in LiNbO3, followed by the development of several
proprietary techniques and inventions relating to integrated optical
devices, including:
- A general integrated optical polarization
converter (an emerging key component for
Polarization-Mode-Dispersion, PMD, compensation systems)
- A self-biased, 1x2 directional coupler modulator
(a complementary-output modulator with operating point automatically set
at zero bias)
- A compact NxN "strictly
non-blocking" optical switch arrays (high-speed switch
matrices for the next-generation of fast optical packet switching)
- A switch with a "digital" step
response (a low crosstalk switch design that greatly relaxes the
stringent requirement on control voltage precision)
- A compact programmable optical time-delay
module (for broadband phased array beam steering and for time-delay
switching for fiber optic systems)
- A universal optical phase control IC
module (a common control module for optically-controlled microwave
phased-array antennas of any RF frequency)
Dr. Thaniyavarn was also the program manager
/ principal investigator for well over ten aerospace programs
including: DARPA "Analog OE Module", "Photonic Networks
for RF Integrated Sensor Systems", "Integrated Wavelength
Cross-Connect Module", etc., and several Air Force, Army and Navy
programs.
Dr. Thaniyavarn received both his B.S. and M.S. in 1978 from Cal Tech. He
earned his Ph.D. (EE) from the U.C. Berkeley working on high-speed optical
semiconductor devices.
Dr.
Gregory L. Abbas (Vice President and
Chief Engineer)
Before
joining EOSPACE in September 1998, Dr. Abbas was an Associate Technical
Fellow of the Boeing Company. He was a key member of the
Integrated Optics/Microwave Photonics Group. During his ten years at
Boeing, he held a wide variety of positions including:
-
Lead system designer of the multi-Gb/s optical inter-satellite
links for the Teledesic program. He
also was involved in system design and analysis of the RF uplink and downlink
phased array antennas on the satellite and for the low-cost user
terminals
-
Lead
designer
of a
low-power burst-mode fiber optic transmitter for a satellite-based
communication system for the Fiber Optic Data Bus (FODB)
contract.
-
Lead communication system engineer for Boeing’s portion of the
1997 Joint Warfare Interoperability Demonstration (JWID ’97).
This project demonstrated airborne reception of data from a fixed
service satellite (FSS) at T1 rates (1.544 Mbps) through Boeing’s
electronically steered phased array antenna.
-
Principal investigator for the Air Force Rome Lab
“Optically-Controlled SHF SATCOM Array” contract, where he studied
multiple architectures for optically-controlled phased array antennas.
-
Demonstration at the Air Force Wright Lab of a 16x16 optical
switch for the DARPA Analog Optoelectronics Module Program
-
Demonstration
of electronic adaptive jammer nulling techniques suitable for
use on structurally integrated apertures
-
Investigation
of optical methods for microwave signal generation including
sideband injection locking and optical phase locking
-
Development
of several high precision laser radar position sensors for aerospace
applications.
Prior
to joining Boeing, Dr.
Abbas was a co-op student and a research assistant at MIT Lincoln Laboratory
in the Optical Communication Technology Group for 7 years. His work there
involved research on optical inter-satellite communication systems.
His masters thesis involved analyzing and demonstrating the first dual-detector balanced
optical heterodyne receiver. He also worked on injection locking of laser
diode arrays and broad area lasers.
Dr. Abbas received both his S.B. (Electrical Eng. & Computer Science) and S.M. (Electrical
Engineering) degrees from Massachusetts Institute of Technology in
1984. He received an E.E. (Electrical Engineering) degree in 1985 and
a Ph.D. (Electrical Engineering) in 1988, also from the MIT. Dr.
Abbas’ Ph.D. thesis work involved developing algorithms for allocating
frequency assignments to multiple classes of traffic in a frequency division
multiplexed local area network.
