The next industrial revolution will arise out of the Internet of Things: vast numbers of devices will exchange copious data at high rates, becoming one of the world's largest hardware technology markets. ****Systems interconnected by copper are limited in data rate and can be degraded by electromagnetic interference. Transferring data onto optical fibre protects against such interference and raises the data rate ceiling, but adds cost of fibre to the copper hardware base. If both data and power can be transferred to optical fibre, systems are simplified, data rate ceilings are raised, costs are reduced, and interference is eliminated.****Optical power links can in principle be achieved using photonic devices based on the extraordinarily rich III-V compound semiconductor materials family, with natural direct bandgap and crystalline quality. Optical power can be generated with III-V laser or LED devices, then carried on multi-mode or single-mode optical fibre, and converted back to electrical power using another III-V device. Key to success is achieving high conversion efficiencies, which theory has shown can approach 100%. ****The ensemble of device and design expertise capable of this architecture has been established in SUNLAB at uOttawa, and at uWaterloo. Present industrial state-of-the-art devices have been demonstrated by our Canadian partner, Azastra Opto, achieving ~70% efficient power receivers. This project will extend this technology to create a new class of devices, previously unavailable, with very high efficiencies capable of supporting commercially viable optical power/data links. The work will be done in two stages: the first stage will demonstrate techniques for improved efficiencies at the present wavelengths; the second stage will add nanostructures (quantum dots) and materials selections at new wavelengths, essential to success.********

下一次工业革命将源于物联网：大量设备将高速交换大量数据，成为世界上最大的硬件技术市场之一。 ****通过铜互连的系统的数据速率受到限制，并且可能会因电磁干扰而降低性能。 将数据传输到光纤上可以防止此类干扰并提高数据速率上限，但会增加铜质硬件基础的光纤成本。 如果数据和电力都可以传输到光纤，系统就会简化，数据速率上限就会提高，成本就会降低，干扰就会消除。****原则上，光电力链路可以使用基于超凡技术的光子器件来实现。丰富的III-V族化合物半导体材料家族，具有天然的直接带隙和结晶质量。 光功率可以使用 III-V 族激光器或 LED 设备产生，然后通过多模或单模光纤传输，并使用另一个 III-V 族设备转换回电能。 成功的关键是实现高转换效率，理论表明转换效率可以接近 100%。 ****支持该架构的器件和设计专业知识的集合已在渥太华大学和滑铁卢大学的 SUNLAB 中建立。 我们的加拿大合作伙伴 Azastra Opto 已经展示了目前最先进的工业设备，可实现约 70% 的功率接收器效率。 该项目将扩展该技术，创建以前无法提供的新型设备，具有非常高的效率，能够支持商业上可行的光功率/数据链路。 这项工作将分两个阶段完成：第一阶段将展示提高当前波长效率的技术；第二阶段将增加纳米结构（量子点）和新波长的材料选择，这是成功的关键。********
