【摘要】：光邏輯門是未來全光網(wǎng)絡(luò)中光信息處理的核心元件,它可以實現(xiàn)高速光包交換,全光地址識別,數(shù)據(jù)編碼,奇偶校驗,信號再生等功能。采用微環(huán)諧振器設(shè)計了一種新型的電光邏輯門,結(jié)構(gòu)通過三個非對稱微環(huán)組成,分析耦合區(qū)的傳輸矩陣方程得出加載電壓信號的變化能夠?qū)崿F(xiàn)微環(huán)折射率的變化,利用光強(qiáng)的邏輯開關(guān)特性可以實現(xiàn)光門邏輯。計算機(jī)仿真驗證了工作波長1 600 nm時,實現(xiàn)的高電平50.7 V定義為邏輯1,低電平0 V定義為邏輯0,通過光強(qiáng)變化得出了6位邏輯運算;整個系統(tǒng)的響應(yīng)時間理論上得到了1.8 ps,運算速率可達(dá)近200 Gbit/s。邏輯的雙穩(wěn)態(tài)分析中得出:微環(huán)發(fā)生最大諧振值時對應(yīng)的控制波長等于微環(huán)未發(fā)生形變前的諧振波長和偏移量之和;調(diào)制可以通過微環(huán)諧振波長實現(xiàn)控制。這一研究對于未來全光通信的實現(xiàn)具有一定的意義。
[Abstract]:Optical logic gate is the core element of optical information processing in future all-optical network. It can realize the functions of high-speed optical packet switching, all-optical address recognition, data coding, parity check, signal regeneration and so on. A new type of electro-optic logic gate is designed by using a microloop resonator. The structure is composed of three asymmetric microrings. By analyzing the transfer matrix equation in the coupling region, it is concluded that the change of the loading voltage signal can realize the change of the refractive index of the microloop. The optical gate logic can be realized by using the characteristics of light intensity logic switch. The computer simulation shows that the high level 50.7 V is defined as logic 1, and the low level 0 V is defined as logic 0 when the working wavelength is 1,600 nm. The 6 bit logic operation is obtained by changing the intensity of light. The response time of the whole system is theoretically 1. 8 ps, up to nearly 200 Gbit/s.. In the bistable analysis of logic, it is concluded that the control wavelength corresponding to the maximum resonant value is equal to the sum of the resonant wavelength and the offset before the microloop does not deform, and the modulation can be controlled by the resonant wavelength of the microloop. This research has certain significance for the realization of all-optical communication in the future.
