Power and spectral range characteristics for optical power converters

Abstract

High-performance optical power converters (OPCs) enable isolated electrical power and power beaming applications at new wavelengths and higher output powers. Broadcom’s vertical epitaxial heterostructure architecture (VEHSA) multi-junction OPCs permit optical-to-electrical conversion at high efficiency and at manageable external loads. This study provides details of how the power outputs have been extended from <1 W to a power class at ~3 W and another class at >20W. The work also provides details of how the spectral range options have been extended from 800-830 nm to other key laser diode wavelengths such as 960-990 nm and 1500-1600 nm.
