Research Abstract

We have investigated high-performance wavelength conversion devices fabricated using semiconductors exhibiting quadratic optical nonlinearities. We have optimized process conditions for fabricating low-loss periodically-inverted GaAs/AlGaAs waveguiding quasi-phase-matching (QPM) devices in order to achieve higher conversion efficiencies. The obtained lowest propagation loss was 1.3 dB/cm at the wavelength of 1.55 um. We have performed a numerical simulation on performances of current-injected AlGaAs QPM devices for the first time. We have revealed that practical current densities lead to net gains and thus extremely high conversion efficiencies. We fabricated a periodically-inverted GaAs pn-junction device for the first time, and evaluated its electrical and optical properties.
