ABSTRACT
It was experimentally observed that low-frequency intensity noise in 1.3 μm semiconductor lasers can be translated to high frequencies through beating with a high-frequency modulation signal, thus imposing a maximum achievable signal/noise ratio. An analysis of this effect using a formalism developed for treating intermodulation distortion yields good agreement with the experimental results.
