摘　　要：为改善光学可调谐滤波器的不足——无法满足非接触、无机械部件、无外部电路驱动,研制了还原氧化石墨烯纳米粒子掺杂的光致聚合物,并记录了全息体光栅。在光致热效应下,该光栅的衍射光谱能够产生相应的波长快速移动,从而调谐输出光波长。试验优化了纳米粒子的最优掺杂比例,并对比测试了光热可调谐滤波性能。结果证明,基于光致聚合物的全息体光栅能够快速、大范围、可逆的调谐衍射光波长,实现滤波器的能力。In order to improve the optical tunable filter shortag,can t be non-contact,no mechanical components,no external circuit drive,the reduced graphene oxide nanoparticles doped photopolymer was developed,and the holographic volume grating was recorded.Under the photothermal effect,the diffraction spectrum of the grating can produce the wavelength shift rapidly,so as to tune the output wavelength.The optimal doping ratio of nanoparticles was optimized,and the photothermal tunable filter performance was compared.It show that the holographic volume grating based on photopolymer can tune the wavelength of diffracted light rapidly,in a large range and reversibly under the photothermal effect,and realize the ability of the filter.
