In this paper, we experimentally present a novel, all-optical spectral efficient vertical-cavity surface-emitting laser- (VCSEL-) based technique for routing and spectrum assignment in optical networks. Exploiting all optical VCSEL-to-VCSEL injection to attain cross gain modulation, the optical transmitter is optimized for optical transmission paths to assure quality of service by overcoming blockage for differentiated bandwidth demands during network congestion incidences. A 10 Gbps directly modulated 1549 nm master VCSEL is optically injected into the 1549 nm side modes of a 1550 nm slave VCSEL. The Shannon limit is considered for higher transmission rates with the problem decomposed into degraded routing and spectrum assignment and chromatic dispersion in the optical transmission link penalties. In this work, the proposed technique achieved a 1.3 dB penalty for transmission over a 25 km G.655 nonzero dispersion-shifted single-mode optical fibre, a value within the transmission media and optical system characteristics of 3 dB as recommended by the International Telecommunication Union-Telecommunication (ITU-T). The number of transceivers, switches, and optical transmission links in the network was reduced, increasing the number of satisfied bandwidth requests, thus optimizing the spectral resource utilization.

基于交叉增益调制的全光VCSEL至VCSEL注入用于光纤传输链路中多节点灵活频谱优化的路由

在本文中,我们实验性地提出了一种新颖的,全光谱有效的垂直腔面发射激光器(VCSEL-)技术,用于光网络中的路由和光谱分配。利用所有VCSEL至VCSEL的光注入技术来实现交叉增益调制,该光发射器针对光传输路径进行了优化,以通过克服网络拥塞发生时对差分带宽需求的阻塞来确保服务质量。将10 Gbps直接调制的1549 nm主VCSEL光学注入到1550 nm从VCSEL的1549 nm侧模中。考虑到香农极限以用于更高的传输速率,该问题分解为光传输链路损失中的路由选择和频谱分配以及色散降低。在这项工作中,所提出的技术达到了1。在25 km G.655非零色散位移单模光纤上传输时,传输损耗为3 dB,根据国际电信联盟(ITU-T)的建议,传输介质和光学系统特性中的值应为3 dB。减少了网络中的收发器,交换机和光传输链路的数量,增加了满足带宽请求的数量,从而优化了频谱资源的利用率。
