Abstract

It is well known that the semiconductor lasers, are susceptible to optical feedback from discrete interfaces or from distributed scattering such as in optical fiber medium. Feedback will affect the spectral property and the stability of the laser output. A number of dynamical behaviors, period doubling route, quasiperiodic route, and bistability, have been found[1–4]. In this letter we report the studies of routes to chaos of single mode laser diode output subjected to a variety of external cavity length. The studies of such effects are important not only for understanding of laser dynamical properties but also for applications of lasers in various systems.
