Two types of hybrid silicon tapers are studied. Single taper loss is 0.3 – 0.5 dB, enabling integration of III/V actives on silicon-on-insulator passive circuitry with low loss. Keywords-Hybrid integration, silicon-on-insulator technology
The first integrated multiwavelength laser based on an arrayed waveguide grating (AWG) fabricated on a silicon-on-insulator wafer is presented. It consists of Fabry–Perot cavities integrated with hybrid silicon amplifiers and an intracavity filter in the form of an AWG with a channel spacing of 360 GHz. Four-channel lasing operation is shown. Single-sided fiber-coupled output powers as high as 35...
