光纤熔锥耦合器的声光调制特性
Characters of Acousto-Optic Intensity Modulation Based on Optical Fiber Fused Taper Coupler
摘要
对光纤熔锥方向耦合器的声光强度调制特性进行了实验研究,得到了工作波长为1310 nm、声波频率为20.19 kHz、电驱动功率为2.6 mW、插入损耗为0.5dB、调制深度为64%的声光强度调制特性.
Abstract
Based on couple modes theory and acoustic optic effect, a monolithic single mode fiber acousto optic intensity modulation based on fused taper coupler is demonstrated at a wavelength of 1310 nm. About 64% modulation was achieved at a modulation frequency of 20.19 kHz, for an electrical drive power of about 2.6 mW.
