低功耗高性能的新型硫系玻璃光纤声光调制器
Low-power high-performance fiber-coupled acousto-optic modulator based on novel chalcogenide glass
摘要
Abstract
Chalcogenide glasses,with their broad infrared transmission window and high acousto-optic figure of merit,represent an ideal medium for low-power high-performance acousto-optic modulators,potentially overcoming the diffraction efficiency and power consumption limitations of acousto-optic modulators based on conventional materials.Ge21 Sb18 S61 chalcogenide glass,characterized by its wide infrared transparency and high refractive index,was systematically investigated for its thermal,physical,optical,and acoustic properties.Using this glass as acousto-optic medium,a high-performance fiber-coupled acousto-optic modulator was successfully fabricated.Experimental results show that under a radio frequency driving power of 0.52 W,the modulator achieves a diffraction efficiency of 84%,a rise time of 41 ns,and an extinction ratio as high as 61 dB,exhibiting excellent low-power consumption and high-efficiency characteristics.This study provides crucial technical support for the design and development of novel acousto-optic devices,contributing to advancements in high-speed optical communication and fiber sensing applications.关键词
