Paper Abstract

When a semiconductor laser is coupled to an optical fiber without an isolator sharp intensity noise spikes can occur due to Rayleigh backscatter. It is shown that these spikes can be suppressed by self locking the laser with a discrete reflection of magnitude comparable to Rayleigh backscatter. This approach is of interest for certain low-cost lightwave applications such as the subscriber ioop where the use of optical isolators may not be desirable due to cost constraints.
