Abstract

A new method to investigate fast frequency modulation of a laser diode by applying optical pulse irradiation is presented. The self-delayed heterodyne technique and an autocorrelation method are used to detect beat in the heterodyne signal due to frequency shift by the irradiation. Autocorrelation of the beat signal is suggested to be calculated via its spectrum.
