Silicon photonics is expected to reduce size and cost of photonic devices and realize large scale photonic integrated circuits for telecom and datacom applications. In this paper, we demonstrate a compact wavelength tunable laser module using hybrid integrated semiconductor optical amplifier and silicon waveguide resonators. The power consumption of the laser module is 1 W to obtain +8 dBm fiber coupled power under the module temperature of 70°C. Such integration technology broadens design flexibility of silicon-based photonic devices and their applications.
