【摘要】：飛速發(fā)展的納米集成技術(shù)使得集成在單個芯片上的處理核的數(shù)量與日俱增,進而迫使芯片上的主干網(wǎng)絡(luò)必須同時處理更多的信息。由于傳統(tǒng)金屬互連網(wǎng)絡(luò)具有高功耗、高延遲、低帶寬等劣勢,因此,采用傳統(tǒng)的金屬布線方式實現(xiàn)芯片上處理核之間的互連已經(jīng)成為阻礙集成密度高的芯片上多核通信系統(tǒng)快速發(fā)展的主要因素之一。此時,光互連技術(shù)應(yīng)運而生并憑借其無與倫比的優(yōu)勢(低損耗、高帶寬、低延遲等)迅速受到眾多研究者的青睞。隨著人們對光互連技術(shù)的研究不斷深入,光互連方式已經(jīng)被人們認為是能夠取代芯片上多核通信系統(tǒng)中傳統(tǒng)金屬互連方式最熱門的候選者,因此,芯片上光互連網(wǎng)絡(luò)(optical network-on-chip,ONoC)也受到了人們的重視。隨著現(xiàn)代通信網(wǎng)絡(luò)中通信數(shù)據(jù)量的日益增加,為了進一步提高芯片上光互連網(wǎng)絡(luò)的通信帶寬,人們將波分復用技術(shù)(wavelength division multiplexing,WDM)引入到了芯片上光互連網(wǎng)絡(luò)中。由于WDM技術(shù)可以有效地提高芯片上光互連網(wǎng)絡(luò)的通信帶寬,使其受到眾多研究者的關(guān)注,所以基于WDM技術(shù)的芯片上光互連網(wǎng)絡(luò)成為了研究者們探索的熱點之一。然而WDM技術(shù)在提高芯片上光互連網(wǎng)絡(luò)通信帶寬的同時也帶來了一些不良的現(xiàn)象,例如,四波混頻效應(yīng)(four-wave mixing,FWM)。芯片上光互連網(wǎng)絡(luò)是芯片上多核通信系統(tǒng)的重要組成部分之一,其核心部件就是芯片上光路由器。所以,光路由器品質(zhì)的優(yōu)劣會對芯片上光互連網(wǎng)絡(luò)乃至整個芯片上多核通信系統(tǒng)的性能造成很大影響。因此,為了深入了解片上網(wǎng)絡(luò)的特點以進一步促進今后多核通信系統(tǒng)的發(fā)展,對片上光路由器進行深入的研究是片上光網(wǎng)絡(luò)發(fā)展歷程中不可或缺的一部分。本文主要對支持單波和WDM技術(shù)的N端口光路由器的基本特性進行探索,提出了支持單波和WDM技術(shù)的N端口光路由器的理論模型,并搭建仿真平臺進行仿真。利用此理論模型能夠研究信號的傳輸損耗、串擾噪聲、光信噪比(optical signal-to-noise ratio,OSNR)、和誤碼率(bit error rate,BER)等。仿真平臺能夠研究信號在光路由器內(nèi)部的傳輸特性。研究結(jié)果表明,隨著光路由器端口數(shù)量的不斷增加,信號在光路由器中傳輸時的平均信噪比逐漸降低。例如,信號在基于單波的五、六、七和八端口光路由器中傳輸時,信號的平均信噪比分別為2.27dB、1.24dB、0.37dB、-0.37dB。在同一信道中傳輸?shù)牟煌ㄩL的信號,其損耗存在著一定的差異,例如,在五端口光路由器的0-2信道中,波長為1542.1nm的信號的功耗為-2.72dB,而波長為1545.3nm的信號的功耗為-3.10dB。在不同信道中傳輸?shù)耐恍盘?其功耗也有差異,比如,波長為1540.5nm的信號在五端口光路由器的不同輸入輸出端口之間傳輸時,其傳輸損耗的變化范圍為-5.66dB~-0.99dB。另外,對于其它幾個性能指標(串擾噪聲、信噪比、誤碼率)也有著同樣的現(xiàn)象發(fā)生。
[Abstract]:With the rapid development of nanointegration technology, the number of processing cores integrated on a single chip is increasing, which forces the backbone network on the chip to process more information at the same time. Because of the disadvantages of traditional metal interconnection networks, such as high power consumption, high delay, low bandwidth and so on, Using traditional metal wiring to realize interconnect between processing cores on chip has become one of the main factors hindering the rapid development of multi-core communication systems with high integration density. At this time, optical interconnection technology emerges as the times require, and with its unparalleled advantages (low loss, high bandwidth, low delay, etc.), it is quickly favored by many researchers. With the development of optical interconnection technology, optical interconnection is considered to be the most popular candidate to replace the traditional metal interconnection in multi-core communication systems on chip. On-chip optical interconnection network (optical network-on-chip,ONoC) has also been paid attention to. With the increasing amount of communication data in modern communication network, in order to further improve the communication bandwidth of on-chip optical interconnection network, (wavelength division multiplexing,WDM (wavelength Division Multiplexing) technology is introduced into the on-chip optical interconnection network. Because WDM technology can effectively improve the communication bandwidth of on-chip optical interconnection network, it has attracted many researchers' attention, so the on-chip optical interconnection network based on WDM technology has become one of the hot spots of researchers. However, WDM technology not only improves the communication bandwidth of on-chip optical interconnection networks, but also brings some bad phenomena, such as four-wave mixing effect (four-wave mixing,FWM). The on-chip optical interconnection network is one of the important components of the multi-core communication system on chip, and its core component is the on-chip optical router. Therefore, the quality of optical routers will have a great impact on the performance of on-chip optical interconnection network and the whole multi-core communication system. Therefore, in order to understand the characteristics of on-chip network and further promote the development of multi-core communication system in the future, the research on on-chip router is an indispensable part of the development of on-chip optical network. In this paper, the basic characteristics of N-port optical router supporting single wave and WDM technology are explored. The theoretical model of N-port optical router supporting single wave and WDM technology is proposed, and the simulation platform is built. The theoretical model can be used to study the signal transmission loss, crosstalk noise, optical signal-to-noise ratio (optical signal-to-noise ratio,OSNR), and bit error rate (bit error rate,BER). The simulation platform can study the transmission characteristics of the signal inside the optical router. The results show that with the increase of the number of ports in optical routers, the average signal-to-noise ratio (SNR) of signals transmitted in optical routers decreases gradually. For example, the average signal-to-noise ratio (SNR) of signals transmitted in single-wave optical routers based on five, six, seven and eight ports is 2.27dBU 1.24dBU 0.37dBg-0.37dB. There are some differences in the loss of different wavelengths of signals transmitted in the same channel. For example, in the 0-2 channel of five-port optical router, the power consumption of the signal with wavelength 1542.1nm is -2.72 dB, and that of signal with wavelength of 1545.3nm is -3.10 dB. The power consumption of the same signal transmitted in different channels is also different. For example, when the signal with wavelength 1540.5nm is transmitted between different input and output ports of the five-port optical router, the range of transmission loss is -5.66 dBU -0.99 dB. In addition, several other performance indicators (crosstalk noise, signal-to-noise ratio, bit error rate) also have the same phenomenon.
