Abstract :
We demonstrate an optically-pumped hybrid silicon evanescent microring laser fabricated by a self-aligned process. Low threshold carrier densities (<2.5times1018 cm-3) are measured for both 15 and 25 mum diameter devices. Lasing up to 50degC is achieved with 0.1 nm/degC wavelength red shift rate.
