We report an eight-channel silicon evanescent laser array operating at continuous wave under room temperature conditions using the selective-area metal bonding technique.The laser array is realized by evanescentl.y coupling the optical gain of InGaAsP multi-quantum wells to the silicon waveguides of varying widths and patterned with distributed Bragg reflector gratings.The lasers have emission peak wavelengths in a range of 1537-1543 nm with a wavelength spacing of about 1.0 nm.The thermal impedances Z_T of these hybrid lasers are evidently lower than those DFB counterparts 相似文献
