Abstract
We experimentally demonstrate a 240-fold increase in the efficiency of an AlGaAs/AlAs surface-emitting second-harmonic generation device by embedding the waveguide core in a monolithic vertical resonant cavity. Calculations indicate that conversion efficiencies of several percent per watt for second-harmonic generation of green or blue light may be expected in an optimized semiconductor resonant vertical-cavity surface emitter.
