Abstract :
Nonlinear distortion associated with the phase characteristic of injection-locked lasers (ILLs) employed as non-regenerative repeaters for optical frequency shift keying (FSK) is considered. A compact expression is derived which shows that this phenomenon can have a significant limiting effect on the performance of a system making use of ILLs as repeaters or as receiver preamplifiers.
