Fiber effective length
WebJul 10, 2006 · In this paper, we describe the properties of Fabry-Perot fiber cavity formed by two fiber Bragg gratings in terms of the grating effective length. We show that the grating effective length is determined by the group delay of the grating, which depends on its diffraction efficiency and physical length. We present a simple analytical formula for ... WebFigure 1: Effective length of a nonlinear fiber is a function of the true fiber length (solid curve). The propagation losses are 0.25 /km (corresponding to 1.085 dB/km). For long fibers, the effective length is limited to 4 km, …
