Abstract
A simple expression for the amplified spontaneous emission from a lase r biased below lasing threshold is applied to semiconductor laser para meter extraction. We demonstrate that accurate measurement of the coup ling coefficient for distributed feedback (DFB) lasers with phaseshift s and end reflections is a practical possibility. It is also shown tha t the used expression, for a reciprocal device, can be derived directl y from the wave equation using the Green's function.
