Abstract :
A technique for stabilizing the center frequency of a short cavity DBR fiber grating laser is reported. This method employs an all-fiber unbalanced-arm scanning Michelson interferometer as a frequency discriminator. Long-term frequency fluctuation of the tested fiber grating laser was improved from /spl plusmn/480 MHz to less than /spl plusmn/30 MHz.
