Abstract

In this paper, modeling of semiconductor diode lasers by sampling the cavity of the laser using digital techniques is presented. These models, that sample the cavity of the semiconductor laser simulating the spread of the field in the active zone, are the only methods that permit evaluation of the spectral behavior of the device. Throughout this work, we present the study of the temporary evolution of the spectrum of the longitudinal modes of a semiconductor laser by using digital simulation techniques. Due to the digital nature of the filter and algorithm, we can adjust any given frequency response and reduce CPU time in computing the results. We present two digital models, DLM and LDDM, which improve the behavior of the traditional methods used in order to obtain temporary spectral response of semiconductor laser diodes.
