Abstract :
We demonstrate an optical scheme allowing for simultaneous wavelength locking and spectral filtering using a single fiber Bragg grating. We observe substantial increase of extinction ratio and reduction of the wavelength chirp. The scheme also provides stable wavelength necessary for dense WDM system applications.
