| 摘 要： | 采用Ag+-Na+离子工艺，在K9玻璃上制备了跑道形波导谐振腔滤波器.测试得到该滤波器自由光谱范围为FSR=0.177 nm，对比对为Cr＝7.5 dB.同时分析得到耦合器的耦合系数为κ=0.916，耦合器和环形腔的损耗因子分别为δ=0.55,γ=0.48.耦合器的两波导几乎相连、条波导边缘不规则和一次离子交换波导表面缺陷是造成该波导滤波器具有较大损耗的主要原因.通过改进工艺技术降低波导损耗，该滤波器可以用于光通信、传感等领域，也可与其它波导结构相结合实现新的功能.

| Abstract: | A racetrack resonator filter is fabricated by Ag+-Na+ ion-exchange technique in K9 glass. The free spectrum rang (FSR) and contrast ratio (Cr) of the resonator are tested to be 0.177 nm and 7.5 dB. With fitted results,the coupling ratio is κ=0.916,the loss factors of the coupler and the resonator are δ = 0.55 and γ = 0.48,respectively. The relative large losses of the waveguide device are due to the almost connection of the coupler waveguides,irregularity of the strip waveguide side and flaw of waveguide surface after one-step ion-exchange. By decreasing loss,this integrated waveguide resonator filter may be used in optics communications or sensing fields and can be combined with other waveguide structures to perform further functions. |
