MONOLITHIC MULTIJUNCTION POWER CONVERTER

摘要

Resonant cavity power converters for converting radiation in the wavelength range from 1 micron to 1.55 micron are disclosed. The resonant cavity power converters can be formed from one or more lattice matched GaInNAsSb junctions and can include distributed Bragg reflectors and/or mirrored surfaces for increasing the power conversion efficiency.
