【摘要】：引入微納光纖、采用絕緣硅(SOI)波導(dǎo)材料,設(shè)計了一種多耦合點的諧振腔濾波器。該濾波器工作方式:當光從入射端輸入,經(jīng)過耦合區(qū)時一部分光會因為倏逝波的存在發(fā)生耦合,耦合進入環(huán)形腔的光在滿足諧振條件時在環(huán)形腔內(nèi)發(fā)生諧振,光在環(huán)形腔中傳播一周后,再次從耦合區(qū)從環(huán)形腔耦合到微納光纖直至輸出。性能分析表明:自耦合系數(shù)的變化不會對光強最大峰值產(chǎn)生影響,可以通過改變傳輸系數(shù)的大小從而實現(xiàn)耦合效率的調(diào)整,品質(zhì)因數(shù)能達到10 000以上,衰減能夠有效控制;通過SOI材料熱膨脹現(xiàn)象實現(xiàn)設(shè)計濾波器的性能控制和光開關(guān)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.
