Senior Principal Optical System Engineering, design of visible and infrared optical systems.

• Signal integrity design and modeling of high-speed circuits for Server Development, IO, and RAID storage controllers. • Validation of critical high-speed circuits such as PCIE, DDR Memory, SAS, Ethernet in Servers and RAID storage controllers.

• Led a team of Optical, Mechanical, Electrical, and Production Engineers spanning multiple locations to design and deliver six Receive Optical Subassemblies (ROSAs) for 10Gb/s operation for three wavelengths (850, 1310, 1550nm), two form factors (LC, SC), Restriction of Hazardous Substance (RoHS) compliancy, and delivered $2.4 million in annual savings.• Designed and implemented 4 Gb/s ROSA for two wavelengths (850, 1310nm), two form factors (LC, SC), RoHS compliancy, and delivered $2 million in annual savings.• Used ZEMAX optical design software to develop integrated Polymer Optical Lens and housings used in fiber optic transceivers for single-mode and multi-mode ROSAs and multimode VCSEL optical fiber coupling.• Developed Labview and Matlab software for automated R&D testing and data analysis of fiber optic transceivers and optical components.• Experimentally and analytically evaluated optical receivers and transmitters for use in fiber optic transceivers.

• Designed optical lenses and optical path layouts for fiber optic Transmit Optical Sub-Assemblies (TOSA) and Receive Optical Sub-Assemblies.• Led team of engineers to design and develop active optical alignment equipment and first article test equipment for optical sub-assemblies and lenses used in fiber optic transceivers.

• Managed team of Optical and Electrical Engineers to develop automated inspection equipment.• Researched and developed laser based inspection equipment for automated inspection and sorting. • Used ZEMAX and Mechanical Desktop 3D CAD and designed innovative high speed laser based inspection and measurement products.• Integrated vision inspection systems into measurement equipment.• Developed Matlab and C++ programs for signal processing and image processing software for high speed inspection systems.• Designed amplifier and filter circuits using PSPICE and Matlab for high speed inspection equipment.

• Developed advanced optical receiver test equipment. • Supported laser warning receiver development team with design and testing of optical receivers.• Developed Testpoint software control of experimental test equipment. • Used Matlab and Mathcad to analyze scintillation data collected during field tests.• Characterized the behavior of a Liquid Mercury Optical Scintillator (LMOS) allowing the USAF to simulate atmospheric turbulence effects on laser beam propagation used to test laser warning receivers.
