At the PHotonic Innovations lab (phi_lab) in ETS we develop novel photonic devices and optical methods aimed at addressing a variety of applications. Here are our main research directions:

A) Design of specialty optical fibers
We design specialty fibers using numerical tools and ensure their fabrication through external collaborators. These specialty fibers are investigated in key application areas such as: next-generation telecommunications, supercontinuum generation and fiber-optic sensors.

B) Space-division multiplexing for next-generation optical communications
Spatial multiplexing is an approach that promises to enhance the capacity of optical communication links by increasing the number of transmission channels within a single strand of fiber. Custom-made specialty optical fibers (few-mode and multicore) are employed in investigations that benefit from the collaboration of researchers at Laval University (see Partners)

C) Cylindrical vector beams and beams with orbital angular momentum

Annular optical beams such as the cylindrical vector beams (with inhomogeneous polarization) and beams with orbital angular momentum (aka "optical vortices") are investigated towards the development of novel optical sensors, imaging devices and for pushing new frontiers in light-matter interactions.

D) Fiber-optic sensors

The small size, low power, fast response and high sensitivity of optical fibers make them ideal tool for the development of sensors for temperature, pressure, strain, humidity, etc. We have among others developed plasmonic fiber-optic humidity sensors and are working on advanced distributed fiber-optic sensors using few-mode fibers.

E) Biophotonics and biomedical devices
In collaboration with the team of Prof. Éric Wagnac, we utilize optical fibers and polymer optical waveguides in various biomedical applications such as: the biomechanical study of spinal cord injuries, and in dentistry. The compact size of optical sensors as well as their high sensitivity allows their efficient integration in clothing, orthotics, prosthetics and many other smart biomedical devices.
