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.
