Novel Integration Approach for III-V Microdisk Cavities on Si

We present and evaluate a novel integration approach for III-V microdisk cavities on Si. We demonstrate InP room-temperature microdisk lasers and compare the performance to similar InP microdisks fabricated via direct wafer bonding. InP allows for future integration of QWs for the NIR spectral range.
