Responsibilities:

Invented a family of tunable filters, tunable interleavers, and tunable add/drop modules (U.S. Patent # 6,438,288). Designed the optics and specified the requirements for components of such devices.

Hired and led a team of electronic, and mechanical engineers. Proved the new tunable filter concept and demonstrated its viability and manufacturability. Built and tested a number of such filters. Conducted device demonstration and presentation to potential customers.

Responsibilities:

MEMS (Micro Electro-Mechanical Systems). He has been involved in MEMS technology since 1994 and investigated its potential for developing small, low cost navigation instruments. Took courses at UC Berkeley in MEMS and attended MEMS conferences on a regular basis.
In charge of the silicon gyro (SiGy) development. Participated in the proposal activities for the Robust Navigator and AM3 (Affordable Multi Missile Manufacturing) that utilize the SiGy.
Worked on the strategic grade Accelerometer - - a joint program between Litton and Draper Lab.
Technical Director and Program Manager, RLG Cost Reduction Programs --Developed eleven projects in RLG design and production process improvement for higher yield and reduced cost. Responsible for technical leadership, program management, and cost accounting of the engineering teams working on the projects.
Worked on the RLG design improvement, bias stability enhancement, and test equipment development. Designed and performed an extensive set of experiments that demonstrated that the passive and active lock-in rates in RLG are the same (publication #17).
Thin Film Coating—developed a method to eliminate coating stress in ion beam sputtering (IBS) deposited dielectric films.
Invented a computer-controlled station to measure the RLG random walk and cavity-driven biases at the alignment stage (empty cavity). The station provides for RLG screening and characterization at an early stage of the production. This station is known as the Passive Lock-in Station at Litton.
Proposed a sputtering technique for the high power laser projects (AVLIS and ICF) at Lawrence Livermore Lab. Obtained two contracts. Developed coating characterization techniques for the projects.
Developed techniques for coating stress reduction. Performed analysis for coating thickness uniformity improvements.
Developed a rugged Tunable Optical Filter for fiber optic communication systems. Obtained a patent (U.S. Patent # 5,430,574) for the device.
3D Display System—Technical Leader and Project Manager. Led a team of scientists and engineers from Cambridge University, Infinity Multimedia (an entertainment technology company) and two divisions of Litton Industries to develop a large screen 3D display system for naked eyes. Demonstrated the system concept and built a prototype.
Proposed a solid block design for the Optical Correlator (a Litton DSD project). Wrote joint proposals and obtained three contracts for the development and delivery of six prototypes. Was Litton GCS Program Manager and Technical Director for the project.

Responsibilities:

DILAG (Differential Laser Gyro. This is known as ZLG at Litton). Design, build, test, and analysis of a DILAG to determine its performance and market potentials.
Passive Cavity Rate Sensor (Publication #10). Experimental investigations in performance characteristics and error mechanisms in the passive cavity rate sensor. Worked on the low-cost, integrated optics implementation of the Concept.
The Phase Conjugate Ring Laser Gyro. Proposed the concept, performed analysis, and conducted experiments for concept demonstration.
In addition to the RLG and other inertial sensors, worked on the development of a number of other optical sensors. Among them are:

NADS: Non-intrusive Air Data Sensor (Publication #6). Proposed the concept, obtained a government contract, performed analysis, and conducted experiments for concept demonstration of an optical interferometric technique for non-intrusive measurement of air data quantities in air vehicles where reduced radar cross section and zero lag are some of the essential requirements
Light Sources for Fiber Optic Sensors. Analysis and design of amplitude and phase modulation in laser diodes (to reduce the coherence length) for use in fiber optic sensors.

Nonlinear Optics. Worked on the applications of nonlinear optics. In addition to the Phase Conjugate RLG, proposed several concepts for FLIR protection using optically nonlinear phenomena and materials. Conducted experiments and analyses in optical bistability and switching effects in HgCdTe (Publication #11). Served as the principal investigator and the program manager of an AFOSR contract for nonlinear optical effects in HgCdTe superlattices. Developed a new technique for characterization of optically nonlinear materials.

Smart Sensors. During 1985-86, served as the principal investigator of a program to develop smart, microprocessor-based, sensors with built-in test and error compensation capabilities. These sensors, intended for use onboard the NASA’s Space Station, represent the concept of distributed intelligence and control to the sensor level. Proposed a plan for application of these techniques to the RLG.
