Reference number : GC-2017-Q4-01699, amendment number : , agreement type : G, recipient legal name : Stansfield, Barry (Institut national de la recherche scientifique), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : This project aims at achieving vertically etched fused silica transmission gratings for optimal_x000D_
visible/near-infrared signal dispersion with minimum zeroth order contribution. The treatment and analysis of_x000D_
such optical signals address a problem of interest for O/E Land Inc., a company that manufactures advanced_x000D_
components for fast and highly sensitive spectrometers, optical instruments and sensors, as well as optical_x000D_
fibers for telecommunication. The proposed research is based on the implementation of plasma and ion-etching_x000D_
techniques to design gratings of etched depths varying between 0.2 and 1.0 µm for optimal first order signal_x000D_
dispersion and maximal optical transmission in the visible/NIR spectral range. These activities will be_x000D_
conducted at INRS in close collaboration with O/E Land's engineers, on fused silica substrates covered by a_x000D_
thin Cr micrometric mask, which will be supplied by the company. After sample processing, both the depth and_x000D_
the uniformity of the etched gratings will be investigated by scanning electron microscopy (SEM), atomic force_x000D_
microscopy (AFM) and/or surface profilometry. The etching parameters will be varied to obtain uniform and_x000D_
parallel grooves with vertical edges. The diffractive optical elements produced during this project will be then_x000D_
integrated into O/E Land instruments, to be tested for specific uses in optical spectrometry and signal_x000D_
processing, thus ensuring an immediate technology transfer. The expected benefits of this project will allow the_x000D_
supporting company to offer new products and reinforce its position in the area of optical instrumentation. It_x000D_
will give INRS the opportunity of consolidating its expertise in the fabrication and characterization of new_x000D_
advanced optical components, for future collaborative projects with the private sector, and more particularly_x000D_
with the Canadian optical industry., program purpose french : This project aims at achieving vertically etched fused silica transmission gratings for optimal_x000D_
