Fast tunable laser diodes are expected to play a crucial role in future optical packet-switched data center and metro networks. We propose a heterogeneously integrated laser diode for fast and wide wavelength tuning. The laser structure consists of III-V tunable twin-guide (TTG) membrane that is adhesively bonded on sampled-grating-containing SOI structures. In this paper, we will present a detailed design analysis of the suggested laser structure. Emphasis is put on the optimisation of the modal gain, tuning efficiency and grating coupling constant. Simulations of an adiabatic tapered coupler to efficiently couple the light from the III-V waveguide to the underlying silicon device layer are presented as well.
