Detectivity and bandwidth limits of cooled and uncooled light detection using nanomechanical resonators
Mathis Turgeon-Roy, Mohammed Shakir, Zachary Louis-Seize +1
Nanomechanical resonators (NMRs) offer a promising alternative to traditional thermal-based radiation detectors due to their immunity to electrical noise. In recent years, these se…
Calibration of Microscope-coupled Fourier Transform Infrared Spectrometers for CW and Modulated Light Emission Measurements
Maxime Brazeau, Mathieu Giroux, Nada Boubrik +1
Measurement of low power infrared light emission spectra from microstructures can be challenging, but is of key importance in several research fields. Fourier transform infrared sp…
Radiator Tailoring for Enhanced Performance in InAs-Based Near-Field Thermophotovoltaics
Mathieu Giroux, Sean Molesky, Raphael St-Gelais +1
Near-field thermophotovoltaics (NFTPV) systems have significant potential for waste heat recovery applications, with both high theoretical efficiency and power density, up to 40% a…
High detectivity terahertz radiation sensing using frequency-noise-optimized nanomechanical resonators
Chang Zhang, Eeswar K. Yalavarthi, Mathieu Giroux +6
We achieve high detectivity terahertz sensing using a silicon nitride nanomechanical resonator functionalized with a metasurface absorber. High performances are achieved by strikin…
