Funded PhD/Postdoc positions in Canada: Quantum communications and metrology using specialty optical fibers

3 Feb 2021

Position Description

The potential applications of optical vortex beams have yet to reach their maturity. One area of vigorous investigation relates to their potential ability to dramatically enhance the data transmission capacity of optical networks through space-division multiplexing (SDM) schemes [1]. Advances in SDM depend notably on the design, fabrication and testing of novel specialty optical fibers [2,3]. Recent works have also shown promising use of optical vortices and SDM in quantum communications and towards a future quantum Internet [4,5].

One of the objectives of a new Research Chair in ETS is to contribute in the development of novel photonic devices (sources, sensors, fibers, etc.) and methods in the field of quantum communications and quantum metrology. The chosen candidate will participate on one or several research projects that will put to work the unique specialty optical fibers, multiple lasers and advanced instruments used for the generation, transmission and monitoring of the vortex beams and their quantum states. A background in quantum optics and/or metrology is desirable for this position. The project will benefit from state-of-the-art facilities in micro-nano-fabrication and characterization capabilities of materials and optoelectronic devices within the LACIME laboratory in ETS, which is welcoming its members this year in new offices as well as expanded lab space and technical capabilities. Our research group is also part of the strategic photonic cluster COPL which offers additional opportunities for networking, internships, technical support, visibility and collaboration.
