Latest Patents

Chan Fernando holds a patent for "Second-harmonic generation in semiconductor heterostructures." This patent describes quasi-phase matched (QPM) second-harmonic (SH) generation in reflection geometry. The SH intensity can be significantly enhanced by spatially modulating the optical properties of the nonlinear medium. This type of quasi-phase matching is demonstrated using an Al.sub.0.8 Ga.sub.0.2 As/GaAs heterostructure designed for .lambda.=1.06 .mu.m incident light. The SH light intensity generated in reflection from the heterostructure is enhanced 70 times relative to the SH response of a homogeneous GaAs wafer. A Fabry-Perot resonant cavity design employs this structure to create thin films with extremely high SH generation efficiencies.
