Abstract :
A thermally tunable microdisk laser integrated on a silicon-on-insulator waveguide circuit is demonstrated. A local heater is fabricated surrounding the microdisk cavity for tuning/trimming the lasing wavelength through the thermo-optical effect. The proposed device can be easily implemented without adding extra fabrication steps. A tuning efficiency of 0.35 nm/mW is obtained. A 2-nm smooth tuning with 20-μW constant lasing power is also demonstrated.
