Abstract

The effect of incoherent optical feedback to a semiconductor diode laser is numerically investigated and the time delay signature of the external cavity is found to exhibit regimentation corresponding to the incoherent feedback. The occurrence of time delay signature and its characteristics such as area of time delay signature distribution and its temporal spread (FWHM) exhibit a definite relation to the regimes of incoherent optical feedback. Turn-on-delay characteristics also exhibit concurring regimentation of incoherent optical feedback to a semiconductor diode laser.
