Abstract :
We report a widely tunable distributed Bragg reflector (DBR) laser, in which InGaAsP with 1.4 μm wavelength emission wavelength is butt-jointed as the DBR material. A Ti thin film heater is integrated in the DBR section of the device. With the help of the tuning effect of the heater, an over 20nm wavelength tuning range is obtained.
