| 摘 要： | 对１．５μｍ波导型声光ＴＥ－ＴＭ模式转换光滤波器进行了研究。采用了可降低驱动功率的表面声波导结构。在１．５￣１．６μｍ波段实现了可调滤光，通带宽度小于２ｎｍ，达到９７￥以上转换率所需的射频驱动功率约８０ｍＷ（１９ｄＢｍ），器件总插入损耗约９ｄＢ。

| Abstract: | The effects of fusion and tapering conditions on biconical taper fiber filters are studied experimentally. A Gaussian profile model for the prediction of fiber taper shape is presented. We have fabricated the passband fiber filter with narrow band (3 dB width 4 nm), and band regection fiber filters with central band rejection wavelengthes of 1553 nm(loss -6.6 dB) and 1559 nm (loss -19.6 dB), respectively. |
