BPN721: Electronic-Photonic Heterogeneous Integration (EPHI) for High Resolution FMCW LIDAR

Abstract Range-finding sensors have applications that span several industries and markets, from metrology to robotic control. In order to penetrate large consumer markets such as 3D imaging for smart-phones or automotive 3D vision, the size and cost of laser detection and ranging (LIDAR) sensors must be reduced by an order of magnitude. By leveraging emerging electronic-photonic integration technology, compact LIDAR sensors with reduction in size/cost can be constructed. We demonstrate the integration of passive Si photonic circuits and CMOS electronic circuits to create a frequency-modulated continuous-wave laser detection and ranging (FMCW LIDAR) source using this technology. Results have shown that electronic-photonic 3D integration of optoelectronic components can greatly improve the performance of FMCW LADAR sources. We demonstrate an FMCW LADAR with 4-micron ranging precision.
