Abstract :
A new effect of an external cavity on the optical power against injected current curve of an AlGaAs laser diode is reported. A simple multimode rate equation model describes this feature and leads to a novel method of measuring the current-dependent frequency deviation in the low-frequency region, without using spectroscopic instrumentation.
