Abstract

A theoretical procedure has been developed for evaluation of the diffraction efficiency of a Reflecting Volume-Bragg-Grating (RVBG) in accordance with Kogelnik’s theory. The diffraction features have been investigated for the different grating thicknesses, refractive index modulation, and grating spatial frequencies, respectively. The linewidths of a diffracted light and the effective diffraction efficiency have been studied while a certain linewidth in spectrum of an incident LD beam is taken into account in the calculation. The results are thought to be useful in the applications of single-longitudinal-mode (SLM) lasers and linewidth narrowing by means of RVBGs.
