Power Analysis and Experimental Study of the Fiber Null Coupler with an Acousto-optic Device
摘要
Abstract
A single-mode fiber acousto-optic (AO) switch based on a null coupler at wavelength of 1. 55 μm is reported. According to the coupled mode theory,power distribution of the null coupler with the acoustic-wave is formulated for general case. Excess loss of 0. 1 dB and the schematic graph of throughput and coupled power are obtained experimentally.
