InP Modulators for Next Generation Coherent Fiber Optic Networks

相干光纤传输系统在光纤通信中开辟了一种新的范例。高速数模转换器、模数转换器和数字信号处理器的进步使系统性能和功能得到了实质性的改善。这些系统还使弹性光网络的概念成为可能，对于弹性光网络，与传统的密集波分复用网络不同，信道载波频率和带宽是灵活的和动态可分配的。这允许通过仅分配特定调制信号所需的带宽来有效利用可用的光谱。这项研究代表了麦吉尔大学和TeraXion之间的一项战略活动，旨在解决弹性和灵活的相干光纤传输系统中的关键挑战：提高网络收发器的性能，同时降低它们的功耗、占地面积和成本。研究的具体目标是：(I)为基于磷化铟(InP)的相干收发机提供实用和成本效益高的技术解决方案，在城域和长途传输网络部门提供所需的性能，以及(Ii)开发设计工具，使能够生产一套符合目标相干光纤传输系统性能的InP设备规范。通过培训加拿大信息和通信部门的高技能人员，这项研究将开发挑战现有技术限制的创新技术，从而为TeraXion和其他加拿大设备制造商创造竞争优势。

Coherent optical fiber transport systems exploit a new paradigm in optical fiber communications. Advances inhigh-speed digital-to-analog converters, analog-to-digital converters, and digital signal processors have allowed substantial improvements in system performance and functionality. These systems also make possible the concept of elastic optical networks for which, unlike conventional dense wavelength division multiplexed networks, the channel carrier frequencies and bandwidths are flexible and dynamically assignable. This allows for efficient use of the available optical spectrum by assigning only the bandwidth needed by a specific modulated signal. The research represents a strategic activity between McGill University and TeraXion that is directed at key challenges in elastic and flexible coherent optical fiber transport systems: increasing the performance of network transceivers whilst simultaneously decreasing their power consumption, footprint, and cost. The specific objectives of the research are to (i) deliver practical and cost effective technological solutions for Indium Phosphide (InP) based coherent transceivers which offer the required performance in both metro and long-haul transport network sectors and (ii) to develop design tools that enable the production of a set of InP device specifications complaint with a target coherent optical fiber transport system performance. Through the training of highly skilled personnel for the Canadian information and communications sector, the research will develop innovative techniques that challenge current technological limits thereby creating competitive advantages for TeraXion as well as other Canadian equipment manufacturers.
