[文摘]:A compact electrically-pumped hybrid silicon microring laser is realized on a hybrid silicon platform. A simplified, selfaligned,deep-etch process is developed to result in low-loss resonator with a high quality factor Q>15,000. Smallfootprint (resonator diameter=50 &mgr;m), electrical and optical losses all contribute to lasing threshold as low as 5.4 mA andup to 65 °C operation temperature in continuous-wave (cw) mode. Outcoupling- and bus waveguide width-dependentstudies are conducted for optimizing device structure. A simple qualitative study in current-voltage (IV) characteristicshows that dry etching through active region leads to <3× more leakage current at the same reverse bias than wet etchcounterpart. It indicates a relatively good interface with tolerable surface recombination from deep dry etch. Thespectrum is single mode with large extinction ratio (>40 dB) and small linewidth (<0.04 nm) observed. The uniquebistability operation in ring resonator structure is also demonstrated.
