BIOGRAPHY
Phillip Sandborn is a PhD Student in the Department of Electrical Engineering and Computer Sciences at UC Berkeley, advised by Prof. Ming Wu. He received his B.S. in Electrical Engineering and B.S. in Mathematics, (both in 2012) at the University of Maryland. His current research interests are in the field of LADAR sensing and, specifically, the development of new architectures and technologies to reduce size, cost, and power consumption of complete LADAR systems.

MEMS-Electronic-Photonic Heterogeneous Integration (MEPHI) Component Fabrication, Design, and Characterization [BPN721]
Active III-V photonic components and passive Si photonic circuits are integrated with CMOS electronic
circuits in this project. The modular MEMS-Electronic-Photonic Heterogeneous Integration (MEPHI) platform will
make use of the high performance of the individual components and integrate (1) MEMS tunable VCSEL with
high-index-contrast grating (HCG) mirrors, (2) photodetectors, (3) Si photonic waveguides, couplers, and
interferometers, (4) high-efficiency vertical optical coupler between III-V and Si waveguides, and (5) CMOS
circuits for frequency control and temperature compensation. In order to demonstrate the capabilities of the
proposed MEPHI platform, a frequency- modulated continuous-wave laser detection and ranging (FMCW LADAR)
source is being developed. Results have shown that electronic-photonic 3D integration of optoelectronic
components can greatly improve the performance of FMCW LADAR sources. We also demonstrate that
optoelectronic integration improves the bandwidth of optical phase-locked loops (OPLLs).
