【摘要】：進(jìn)入21世紀(jì)以后,雖然單模光纖傳輸系統(tǒng)的通信容量已經(jīng)得到了極大幅度的提升,但依舊不能滿足人們對容量上限的需求。在科研人員的不懈努力下,發(fā)現(xiàn)了一種新型的傳輸方式—模分復(fù)用傳輸系統(tǒng)。此項(xiàng)技術(shù)具有能夠大幅度擴(kuò)大傳輸容量的潛力,成為當(dāng)前光纖通信領(lǐng)域內(nèi)研究的熱點(diǎn)課題。模分復(fù)用傳輸系統(tǒng)的特點(diǎn)是以不同的模式作為信息的載體,將少模光纖作為傳輸?shù)逆溌?實(shí)現(xiàn)了一種多輸入多輸出的傳輸模型。其中如何實(shí)現(xiàn)不同模式的高效率轉(zhuǎn)換的問題是模分復(fù)用技術(shù)得到廣泛利用的重要基礎(chǔ),但是在實(shí)際的生產(chǎn)運(yùn)用中,模分復(fù)用系統(tǒng)的傳輸距離受了信號缺失與干擾的嚴(yán)重影響。據(jù)此,本文提出了一種新的傳輸模型來解決這些問題。本文的主要工作和創(chuàng)新點(diǎn)具體包括以下幾個(gè)方面:首先介紹了模分復(fù)用系統(tǒng)的研究背景以及國內(nèi)外的研究現(xiàn)狀,并且對光纖傳輸系統(tǒng)進(jìn)行了詳細(xì)闡述。之后我們詳細(xì)介紹了超對稱光學(xué)結(jié)構(gòu)的形貌和特性,并在此基礎(chǔ)上引入了一個(gè)新型的光學(xué)結(jié)構(gòu),類超對稱光學(xué)結(jié)構(gòu),展示了類超對稱光學(xué)結(jié)構(gòu)中的耦合情況。接下來我們還利用了一種新型的三芯波導(dǎo)來實(shí)現(xiàn)類超對稱傳輸系統(tǒng)的單方向耦合與解調(diào),最終完成了類超對稱模分復(fù)用系統(tǒng)整個(gè)過程高效快速的模式轉(zhuǎn)換。
[Abstract]:In the 21st century, although the communication capacity of single-mode optical fiber transmission system has been greatly improved, it still can not meet the demand of the upper capacity. With the unremitting efforts of researchers, a new transmission mode, module division multiplexing transmission system, has been found. This technology has the potential to greatly expand the transmission capacity, and has become a hot topic in the field of optical fiber communication. The characteristic of mode division multiplexing transmission system is to take different modes as the carrier of information and take the small mode optical fiber as the transmission link to realize a multi-input and multi-output transmission model. The problem of how to realize the efficient conversion of different modes is an important basis for the widespread use of module division multiplexing technology. However, in the practical application, the transmission distance of module division multiplexing system is seriously affected by the lack of signal and interference. Therefore, a new transmission model is proposed to solve these problems. The main work and innovations of this paper include the following aspects: firstly, the research background of module division multiplexing system and the research status at home and abroad are introduced, and the optical fiber transmission system is described in detail. Then we introduce the morphology and characteristics of the supersymmetric optical structure in detail, and introduce a new type of optical structure, which is similar to the supersymmetric optical structure, which shows the coupling of the supersymmetric optical structure. Then we use a new kind of three-core waveguide to realize the unidirectional coupling and demodulation of the supersymmetric transmission system, and finally complete the mode conversion of the whole process of the supersymmetric mode division multiplexing system.
