Abstract: Recent progress in the field of fiber Bragg grating (FBG) sensors and devices is translating into important contributions in various areas including infrastructure monitoring and medical devices. The Advanced Photonic Components laboratory (APClab) of Carleton’s Department of Electronics has greatly contributed to this effort through the development of a multitude of innovative tilted FBG-based mechanical and biochemical sensors. Building on this work as well as recent advances in other fields, there are many compelling avenues that can be undertaken by the APClab in the coming years. Three
such promising FBG-based technological developments are discussed in this presentation: on-fiber multiplex DNA detection, light-driven diarylethene-based actuators, and novel Brillouin and Raman spectroscopy methods. In each case, a directly or indirectly related previous research effort is first discussed: a proof-of-concept fiber device for gene detection; the molecular movie of the ring closing
reaction in crystalline diarylethene, and the development of new Fabry-Perot-based picometer resolution spectrometers. Related future research endeavors proposed for the APClab are then outlined. The proposed research could greatly improve the efficiency and accessibility of point-of-care DNA testing, unlock new capabilities in light-actuated microrobotics, and allow a deeper understanding of
spin wave propagation in the promising context of magnonic devices.
Bio: Dr. Hubert Jean-Ruel is an optics and photonics researcher with a BSc Honours physics degree from Laval University and a PhD in ultrafast optics from the University of Toronto. He completed a postdoctoral fellowship in the Department of Electronics of Carleton University with a pioneer in the
field of fiber Bragg grating sensors. He led the photonics side of an interdisciplinary project in collaboration with other departments and with the company Spartan Bioscience. He is currently the spectrometer product manager of the company LightMachinery Inc. After co-creating the spectrometer department, he now leads the research efforts to develop new picometer resolution spectroscopy technologies.
