Abstract :
Two types of athermal wavelength locker, which use a fiber Bragg grating and a fiber Bragg grating etalon were demonstrated. Each type operates stably without thermal control as a single wavelength locker and a multi-channel wavelength locker, respectively. Thermal wavelength drift of the laser diode was less than 25 pm for the FBG type and 40 pm for the FBG etalon type in the temperature range from -5°C to 70°C.
