Abstract :
The components for monolithic integration of an all-optical frequency converter in GaAs-AlGaAs superlattice-core material system are developed. The wavelength routing is demonstrated with a di-chroic multimode interference coupler, which has minimum crosstalk of -12 and -7 dB at the signal and pump wavelengths, respectively. Continuous-wave stimulated emission at 801 nm has been achieved at room-temperature in a half ring superlattice laser, which can be exploited as an on-chip pump laser sources.
