Zusammenfassung:Short wavelength laser sources, such as green laser sources, have found increased applications. Laser wavelengths, such as green light, which cannot be generated by a single native semiconductor laser source, can be obtained using the nonlinear susceptibility of many optical materials. For green laser sources capable of high speed modulation, the combination of a quasi-phase-matched second harmonic generation (SHG) waveguide device and a single-wavelength distributed-Bragg-reflector (DBR) laser diode is promising. The wavelength conversion efficiency of a SHG is strongly dependent on the wavelength matching between the DBR laser diode and the SHG device, posing a significant challenge in green laser packaging. It is desired that the wavelength matching is achieved at high efficiency and thus low power consumption. In this paper, the wavelength matching between a DBR laser diode and a SHG device is discussed and thermal wavelength tuning of both laser and SHG device is designed and studied
