The heterogeneous wavelength tunable laser combining quantum dot and silicon photonics technology is proposed. Ultra-compact tunable laser with 8.8 THz frequency tuning range was successfully demonstrated around 1.25 mm wavelength. The heterogeneous wavelength tunable laser will become breakthrough technology for high capacity data transmission system.
