Anti-reflection subwavelength gratings for waveguide facets in the mid-infrared

Nooman El Bouchikhi, Annabelle Bricout, Victor Turpaud, Stefano Calcaterra et autres

Mid-infrared (IR) spectroscopy is a universal way to identify chemical and biological substances. Indeed, several molecules, such as carbon dioxide or ammoniac, have their fingerprint region in the mid-infrared wavelength range. Silicon (Si) photonics pave the way for making on-chip midinfrared spectroscopy. …
