ABSTRACT:
A long wavelength VCSEL according to the present invention is optically coupled to and optically pumped by a shorter wavelength, electrically pumped VCSEL. Short wavelength radiation emitted from the top surface of the underlying VCSEL is transmitted through the lower mirror of the long wavelength VCSEL. Long wavelength radiation is preferably emitted from the top surface of the long wavelength VCSEL. The two VCSELs are preferably joined together using a transparent optical adhesive, a wafer-fusing process, or a metal to metal bond.
