Small signal intensity modulation of external cavity lasers with fiber Bragg gratings

Abstract

The small signal intensity modulation (IM) of a hybrid soliton pulse source (HSPS) utilizing Gaussian apodized fiber Bragg grating (FBG) is described using electric field approach. The HSPS is modeled by a time-domain solution of the coupled-mode equations. It is shown that type of external cavity is important effect on resonance peak spectral splitting (RPSS) in IM response as well as effect of laser and FBG parameters. It is also shown that the RPSS can be suppressed by using linearly chirped Gaussian apodized FBG as an external cavity insted of Gaussian apodized FBG.

“…AR coating reflectivity 0.01, HR coating field reflectivity 0.9, and gain compression factor 2x10 -17 cm 3 . The other MQW laser diode parameters can be found [4][5][6].…”

“…The geometry is same as the one reported in [4][5][6]. One facet of diode is high reflectivity (HR) coated and the other antireflection (AR) coated.…”
