Abstract

We report here the design and experimental demonstration of optically pumped photonic crystal bandedge membrane lasers on silicon-on-insulator (SOI) and on bulk silicon (Si) substrates, based on heterogeneously integrated InGaAsP multi-quantum-well membrane layers transfer printed onto patterned photonic crystal cavities. Single mode lasing under room-temperature operation was observed at 1542 nm, with excellent side mode suppression ratio greater than 31.5 dB, for the laser built on SOI substrate. For the laser built on bulk Si substrate, the improved thermal characteristics are favorable for lasers operating potentially at higher temperatures and higher power. We also report the experimental and theoretical investigations of the lateral size effects associated with the finite cavity dimension. Finally, buried tunnel-junction (BTJ) has been employed for electrical pumping operation. The electrically pumped PCSEL on Si substrate was demonstrated.
