Continuous Wave Blue Lasing in III-Nitride Nanobeam Cavity on Silicon

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Noelia Vico Triviño

IIIV photonics on silicon is an active and promising research area. Here, we demonstrate room-temperature (RT) lasing in short-wavelength III-nitride photonic crystal nanobeam cavities grown on silicon featuring a single InGaN quantum well (QW). In the low ...
