| 摘 要： | 采用AgNO3、KNO3混和熔盐作为离子交换源,在K9玻璃上制备了跑道形谐振腔滤波器。测试得到该滤波器的自由光谱范围为0.178 nm,两个输出端口的衬比度分别为1.47 dB和6.5 dB,分析得到耦合器的分束比和谐振腔的传输损耗分别为к=0.16和α=8.1 dB/cm。利用热光效应在16℃的温度变化范围内,滤波器实现了2π的相位调制,同时分析得到波导材料的热光系数约为1.28×10-5/℃。

| Abstract: | A racetrack waveguide resonator filter was fabricated on K9 glass by ion-exchange in mixed melt salt of AgNO3 and KNO3. The free spectral range of the filter was 0.178 nm, and the contrast of the two output ports were 1.47dB and 6.5 dB, respectively. From the measurement parameters, the splitting ratio of the coupler and propagation loss of the resonator were analyzed to be 0.16 and 8.1 dB/cm. The phase shift of 2π was realized by using thermo-optical effect within 16 ℃ temperature change, and the thermo-optical coefficient of the waveguide material was about 1.28×10-5 /℃. |
