Dynamics of the Frequency Shifts in Semiconductor Lasers under the Injection of a Frequency Comb

Abstract

We have numerically investigated the dynamics of frequency shifts in semiconductor lasers under the injection of a frequency comb. We have studied the effect of comb spacing on the locking bandwidth. Frequency comb spacing was found to play an important role in the boundaries of the locking bandwidth as well as in the frequency shift of the SL peak.

“…Additionally, the mode configuration of an excited-state quantum dot laser (ESQDL) under concave mirror optical feedback demonstrating the selective excitation of longitudinal modes was explored [8]. Bian et al proposed a simple method using mutually coupled free-running VCSELs to generate broadband polarization chaos [9], while the locking map of a semiconductor laser under the injection of a frequency comb was studied [10]. Moreover, a new technique using feedback-delay signatures of a modulated semiconductor laser for fiber fault detection was introduced to enhance detection sensitivity [11].…”
