MEMS-Electronic-Photonic Heterogeneous Integration (MEPHI) [BPN678]
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.
