【摘要】：在片上多核处理器系统中,片上光互连网络由于可以提高带宽,减少时延以及降低功耗,可有效解决传统电互连网络发展瓶颈的问题,所以得到广泛的研究和关注。而在片上光互连网络中,光路由器是其关键组件之一,直接影响着片上光互连网络的性能。本论文基于光波导理论和微环谐振理论,利用微环谐振器和聚合物材料/SOI材料的优点,分别优化设计了两种无源和两种有源光路由器;为进一步研究光路由器在光互连网络中的应用,基于OPNET仿真平台,利用无阻塞有源五端口光路由器建立了一种三维Mesh片上光互连网络,并对网络性能进行了初步研究。首先,基于聚合物材料优化设计并数值模拟了交叉耦合双微环谐振器和平行耦合单微环谐振器,使用24组交叉耦合双微环谐振器,设计了一种可路由7种信道波长的八端口光路由器,在1548.4~1553.2 nm范围内间隔为0.8 nm的波长下,八端口光路由器的插入损耗为0.02~0.58 dB,最大串扰-39 dB,芯片尺寸约0.79 mm2。为提高光路由器的通信带宽,在八端口光路由器的基础上设计了一种新型通用的N级级联八端口光路由器,级联后的光路由器可路由7N(N≤43)种信道波长。此外,为降低器件损耗,基于平行耦合单微环谐振器优化设计并数值模拟了一种可路由三种信道波长的新型无源四端口光路由器,它是目前所有四端口光路由器中使用微环数最少的一种,在选定的三个信道波长(1550、1551.6、1553.2nm)下,其沿不同路径的插入损耗为0.02~0.6dB,串扰为-23.41~-37.71dB。其次,基于SOI材料优化设计并数值模拟了两种谐振波长为1550 nm的可热光调谐的平行耦合单微环谐振器,使用4个和8个平行耦合单微环谐振器作为基本路由单元分别理论设计了无阻塞四端口和五端口有源光路由器,通过热光效应调谐每个基本路由单元的谐振,两种光路由器分别具有9种和44种无阻塞路由状态。通过建立理论模型,对两种光路由器的输出光谱、插入损耗、串扰和功耗等性能进行了详细的表征。根据光路由器数据链路的分析得出,无阻塞四端口和五端口有源光路由器的插入损耗分别为0.13~3.36 dB和0.36~1.70 dB,串扰分别为-19.46 dB和-20 dB,功耗分别为0~88 mW和44.2~154.8mW。为进一步提高两种光路由器的性能,对三个串联微环代替单个微环的基本路由单元进行了研究。最后,为进一步研究光路由器的应用性能,基于OPNET仿真平台和有源无阻塞五端口光路由器,初步设计并仿真了一种三维Mesh片上光互连网络。仿真结果显示,在XY维序路由算法下,光信号从源节点到目的节点所经历的功耗和损耗与其所通过的中间节点数目呈线性关系。创新点:第一,基于聚合物材料交叉耦合双微环谐振器,优化设计并数值模拟了一种新型八端口无源光路由器件,其可实现宽光谱多波长信号的定点路由功能。第二,基于聚合物材料平行耦合单微环谐振器,优化设计了一种使用微环数最少且插入损耗较小的新型无源四端口光路由器件。第三,基于SOI波导,设计了两种新型的热光可调谐的平行耦合单微环谐振器,进而设计并研究了两种新型拓扑结构的无阻塞有源四、五端口光路由器件。
[Abstract]:In the on-chip multi core processor system, the optical interconnection network can improve the bandwidth, reduce the delay and reduce the power consumption, so it can effectively solve the bottleneck of the development of traditional electrical interconnection network, so it is widely studied and concerned. In the optical interconnection network, the optical path is one of the key components, which directly affects the light on the chip. Based on the theory of optical waveguide and the theory of microring resonance, two passive and two kinds of active optical routers are designed and designed, respectively, based on the advantages of the microring resonator and the /SOI materials of the polymer materials. The application of the optical router in the optical interconnection network is further studied. The OPNET simulation platform is based on the non blocking. The source five port optical router establishes a three-dimensional Mesh chip optical interconnection network, and studies the network performance preliminarily. First, based on the optimization design of the polymer materials and numerical simulation of the cross coupled double microring resonator and parallel coupled single microring resonator, a routing is designed using 24 sets of cross coupled double microring resonator. 7 channel wavelength eight port optical routers, with a wavelength of 0.8 nm within the range of 1548.4~1553.2 nm, the insertion loss of the eight port optical router is 0.02~0.58 dB, the maximum crosstalk -39 dB, and the chip size about 0.79 mm2. to improve the communication bandwidth of the optical router, and a new general N level is designed on the basis of the eight port optical router. Cascaded eight port optical routers, the cascaded optical routers can route 7N (N < 43) channel wavelengths. In addition, in order to reduce device loss, a new passive four port optical path, which can route three channel wavelengths, is designed and numerically simulated by parallel coupled single microring resonators. It is currently made in all four port optical routers. With the least number of microloops, the insertion loss along different paths is 0.02~0.6dB and the crosstalk is -23.41~-37.71dB. next to the selected three channel wavelengths (15501551.61553.2nm). Based on the SOI material optimization design and the numerical simulation of the parallel coupled single microring resonator with two kinds of resonant wavelengths of 1550 nm, 4 are used. 8 parallel coupled single micro loop resonators are used as the basic routing units to design the non blocking four port and five port active optical router respectively. The resonance of each basic routing unit is tuned by the thermal optical effect. The two optical routers have 9 and 44 non blocking routing states respectively. By establishing the theoretical model, two kinds of optical routers are established. The output spectrum, insertion loss, crosstalk and power consumption are characterized in detail. According to the analysis of the optical router data link, the insertion loss of the four port and five port active optical routers is 0.13~3.36 dB and 0.36~1.70 dB respectively, the crosstalk is -19.46 dB and -20 dB respectively, and the power consumption is 0~88 mW and 44.2~154.8mW. respectively. In order to further improve the performance of two optical routers, the basic routing units of three series microloops instead of single microloops are studied. Finally, in order to further study the application performance of optical routers, based on OPNET simulation platform and active non blocking five port optical routers, a three-dimensional Mesh chip optical interconnection network is designed and simulated. The simulation results show that, under the XY routing algorithm, the power consumption and loss of the optical signal from the source node to the destination node have a linear relationship with the number of intermediate nodes. First, based on the cross coupled double microloop resonator of polymer materials, a new type of eight port passive optical router is designed and simulated. Second, based on the parallel coupled single microring resonator of polymer materials, a novel passive four port optical router which uses the least microloop number and the insertion loss is optimized. Third, based on the SOI waveguide, two new type of thermo optic tunable parallel coupling is designed. Combined with single microring resonator, two new non blocking active four and five port optical routers are designed and studied.
