Abstract :
In this paper, we proposed a novel III-V/SOI heterogeneous distributed feedback laser. Stimulated emission generated in a III-V active waveguide modulated by the underneath silicon sampled Bragg grating results in a four-wavelength laser with 18.5-nm wavelength interval targeting for coarse wavelength-division multiplexing. The four wavelengths can be thermally tuned owing to the thermooptic effect of silicon with tuning bandwidth of 2.4 nm.
