摘要：

The observation of stochastic resonance in a semiconductor distributed feedback laser is reported. Bistable modal and intensity operation is obtained using the degenerate modes of the grating. Through an observation of longitudinal-mode switching under current modulation, an enhancement in the signal-to-noise ratio of the laser's output wavelength switching of 22 dB is measured.
