DYNAMIC TRANSMISSION PROPERTIES OF A NONLINEAR FIBER RING-RESONATOR

We present a method for calculating the dynamic input-output character istics of a nonlinear fiber ring resonator caused by a change in input intensity. It is based on an original method developed by Bischofberg er and Shen [Phys Rev. A 19, 1169 (1979)] to study a transient nonline ar Fabry-Perot resonator. We treat a double-coupler fiber ring resonat or, in which two types of optical bistability (transmission bistabilit y and reflection bistability) are available and present the illustrati ve numerical results fora few cavity parameters. This analysis will be useful for a future experimental verification of optical bistability in fiber ring resonators and for the design of fiber bistable devices. (C) 1995 Optical Society of America
