【摘要】：引入微纳光纤、采用绝缘硅(SOI)波导材料,设计了一种多耦合点的谐振腔滤波器。该滤波器工作方式:当光从入射端输入,经过耦合区时一部分光会因为倏逝波的存在发生耦合,耦合进入环形腔的光在满足谐振条件时在环形腔内发生谐振,光在环形腔中传播一周后,再次从耦合区从环形腔耦合到微纳光纤直至输出。性能分析表明:自耦合系数的变化不会对光强最大峰值产生影响,可以通过改变传输系数的大小从而实现耦合效率的调整,品质因数能达到10 000以上,衰减能够有效控制;通过SOI材料热膨胀现象实现设计滤波器的性能控制和光开关性能。
[Abstract]:A resonator filter with multiple coupling points is designed by introducing micro-nano fiber and using insulating silicon-silicon (SOI) waveguide material. The filter works: when the light is input from the incident end and passes through the coupling region, a part of the light will be coupled because of the existence of evanescent waves, and the light coupled into the ring cavity will resonate in the ring cavity when the resonant condition is satisfied. After the light propagates in the ring cavity for one week, it is coupled again from the ring cavity to the micro-nano fiber from the coupling region to the output. The performance analysis shows that the variation of the self-coupling coefficient will not affect the maximum peak value of light intensity. The coupling efficiency can be adjusted by changing the transmission coefficient. The quality factor can reach more than 10,000, and the attenuation can be effectively controlled. The performance control of the designed filter and the performance of optical switch are realized by the thermal expansion of SOI material.
