Abstract: We utilized the forward transmission matrix method (FTMM) to theoretically examine the transmission and reflection characteristics of distributed feedback chirped grating structures based on graphene arrays. These chirped gratings are formed by embedding single-layer graphene… read more here.

Abstract: Time delay signature (TDS) of a semiconductor laser subject to dispersive optical feedback from a chirped fibre Bragg grating (CFBG) is investigated experimentally and numerically. Different from mirror, CFBG provides additional frequency-dependent delay caused by… read more here.
