Title:
Phase-shifted fibre Bragg grating ring resonator for ultrasensitive temperature and strain measurements
Agreement Value:
$753,025.00
Agreement Date:
Mar 28, 2022 - Sep 30, 2025
Description:
The Project applies quantum sensing to photonic measurements of a ring resonator containing a phase-shifted fibre Bragg grating. Quantum-based interrogation promises to improve the sensitivity of the device by an order of magnitude. For measurements of strain, this will result in a sensitivity at the level of pico-strain. In order to increase the measurement sensitivity beyond the quantum limit (SQL), the interferometer will be probed with a superposition of coherent light and squeezed light (squeezed state of light). A very sensitive balanced homodyne detection will be used to probe the interferometer. A 2 -5 dB decrease in noise level would allow detection of environment perturbation that otherwise would have been lost in the noise. Partnering with FIBOS Inc., who have developed PS-FBG based sensing platforms, the Project will develop interferometric measurement techniques that will be very sensitive to strain, vibration and/or magnetic fields.

Program:
Collaborative Science, Technology and Innovation Program – Ideation Fund
Program Purpose:
The Ideation Fund is intended to encourage, test and validate transformative research ideas generated by teams of NRC scientific personnel and external collaborators with complementary capabilities, acting as a demonstration phase for a continually-evolving suite of research and development (R&D) deliverables at the NRC. The fund supports exploratory research through two mechanisms: the New Beginnings Initiative and the Small Teams Initiative.
