Abstract :
A generalised eigenmode analysis of phased-array diode lasers is presented that takes account of modal overlap between adjacent channels. The effect of the overlap is to modify supermode gain splitting nonuniformly. Current spreading suppresses supermode discrimination, resulting in single-lobed far-field operation of arrays with closely spaced lasers.
