Purpose

Building on the successful demonstration of a compact and low-cost terahertz (THz) spectrometer capable of generating and detecting frequencies from 0.3 to 6 THz, this project will combine this small footprint configuration with a recently demonstrated sensitive THz detection technique based on nonlinear optics, spectral filtering and single-photon detection. The ultimate goal is to demonstrate an ultra-sensitive photonicsbased wireless receiver that operates at frequencies above 0.3 THz to enable short- to medium-range 6G communication speeds and beyond. Patterned phase gratings on nonlinear crystals will be incorporated into the design of the detection system, maximizing the collection efficiency of the THz radiation. A demonstrator of a sensitive and compact THz receiver is anticipated to take place at the end of this project. Additionally, with the University of Ottawa’s industry partner, the project will determine how to most efficiently take this technology to market
