| 摘 要： | 采用DBR/电极/间隔层/电极/DBR的结构形式制作滤波器,器件透光部分刻蚀以消除电光效应.测试滤波器透过率光谱,并通过加电压对滤波器中心波长进行调制.据实际结果得到腔的光学厚度为8.04μm,腔长在电场作用下收缩.在140V电压下,腔长收缩量约为0.757%.实验证明电致伸缩效应在调制中起作用.

| Abstract: | Tunable Fabry-Perot filter (FPF) has high practical value in optic communications. Piezoelectric copolymer P(VDF-TrFE) can be used as spacer material in FPF to obtain large tunability in wide range because of its great electrostrictive effect. The filter has been fabricated with the structure of DBR/electrode/spacer/electrode/DBR. The copolymer is partly etched at where the light traverses. The transmittance spectra have been studied. The resonant wavelengths have been modulated by applied voltage. The opti... |
