Optimization for grating length of 980nm single-mode semiconductor laser with dual fiber Bragg grating (original) (raw)

2009 International Conference on Optical Instruments and Technology: Optoelectronic Devices and Integration, 2009

Abstract

The analytical expression of transmittivity and reflectivity of dual fiber Bragg grating (FBG) and the gain equations of the laser are obtained by the coupled mode theory. The laser gain curve is studied through the length of dual FBG and optical fiber length between two gratings under coherence collapse. The relative parameters have been optimized to get the best mode-stabilizing
