Optical communication solutions today make use of many discrete components, each individually optimized for maximum performance at high speed and fabricated using exotic technologies. Specifically, the components used to convert high-speed light signals into electrical signals are critical and expensive. Our recent research has demonstrated signal processing that allows for the use of an optical-electrical converter that may be fabricated directly alongside electronic circuitry using the same low-cost manufacturing processes. We have already used the technology to demonstrate a complete optical receiver operating up to 5 Gbps, sufficient to transfer an entire Blu-Ray movie in less than 1 minute. The prototype accepts an optical input and produces a digital logic output all on a single silicon die measuring less than 1 square millimetre and fabricated using a mainstream manufacturing technology. The timing of this breakthrough is serendipitous as it coincides with advances in optical fibre technology that are ushering in a new set of exciting applications for optical communication. This project will see the technology incorporated a parallel transceiver capable of transmitting and receiving over multiple parallel optical fibers simultaneously. This proposal outlines a plan to meet this objective and demonstrate a parallel link in 9 months, making the technology ready for transfer to commercialization partners.

当今的光通信解决方案使用许多分立元件，每个元件都单独优化，以实现高速时的最大性能，并使用异国情调的技术制造。 具体而言，用于将高速光信号转换为电信号的组件是关键且昂贵的。 我们最近的研究表明，信号处理允许使用光电转换器，该光电转换器可以使用相同的低成本制造工艺直接与电子电路一起制造。我们已经使用该技术演示了一个完整的光接收器，其工作速率高达5 Gbps，足以在不到1分钟的时间内传输整个蓝光电影。 该原型接受光学输入，并产生数字逻辑输出，所有这些都在一个小于1平方毫米的硅芯片上，并使用主流制造技术制造。 这一突破的时机是偶然的，因为它与光纤技术的进步相吻合，这些技术正在为光通信带来一系列令人兴奋的新应用。 该项目将看到该技术结合了一个并行收发器，能够同时通过多个并行光纤进行发送和接收。 该提案概述了实现这一目标的计划，并在9个月内展示了一个并行链接，使该技术准备好转让给商业化合作伙伴。
