With the increase of capacity demand, bit rate per channel has been increased up to more 100 Gb/s in fiber optic communication systems. Moreover, wireless communications using millimeter-wave band are going to be used in 5G. Photonics assisted millimeter-wave wireless communications have been considered a cost-effective and promising solution. Photonics assisted millimeter-wave generation for measurement equipment has been considered a feasible technique, particularly for frequency of beyond 70 GHz. All the above applications require a key device that is broadband photodiodes/photodetectors. Unfortunately, the technology and expertise of broadband photodiodes are monopolized. By two companies in Japan and Germany; to date, Canadian companies do not have a foothold in this market. This project is going to develop a 100-GHz bandwidth and 10-mW output RF power photodetector with fiber pigtail and 1-mm RF connector. The project will involve in design of InP photodiode chips, fabrication of the chips and optical and electrical packaging of the chips, and finally characterization. The acquired technologies will be transferred to OZ Optics Ltd. In Ottawa. A final report summarizing the design and performance of the photodetector will be transferred to OZ Optics.
