Abstract

The response of a polarization-bistable vertical cavity surface emitting laser to a small amplitude, pseudorandom binary signal is experimentally studied. A high-contrast output is obtained when the optimum amount of noise is added to the system. The quality of the transmission, measured by the bit-error rate, exhibits a resonantlike behavior as a function of the input noise. We analyze possible applications of this transmission scheme to optical communications and compare it with those used in a standard amplitude modulation scheme.
