摘要
We report a novel frequency stabilization scheme for laser diodes. The frequency discriminator is simply a fiber optic coupler which acts as a nearly-balanced-arm fiberoptic Michelson interferometer. It is estimated that the frequency fluctuation of our test laser (λ = 0.83 μm) stabilized by this method is less than ± 4 MHz. This scheme is applicable to longer wavelength (1.2-1.6 μm) laser diodes and the stabilized lasers can be packaged easily. © 1990 IEEE
