Abstract :
Wavelength stabilization at multiple wavelengths of a DBR laser using fiber gratings has been achieved. The wavelength is stabilized to approximately 0.1 nm even though the laser temperature is varied 10°C. We demonstrate the use of multiple UV-written gratings in a single fiber to control the wavelength stablity of different modes of a three-section DBR laser. The work demonstrates a principle which can be extended to control widely tunable four-section lasers
