Request InfoChiral Photonics Inc.Based on proprietary technology, chiral long period gratings from Chiral Photonics can optically sense environmental factors such as chemical composition, temperature and pressure. They are sensitive to circularly polarized light that has the same handedness as the chiral fiber. Light that is oppositely polarized can be used for control purposes or can serve as a second sensing channel. The gratings are structurally formed into fiber and stable at high temperatures. They can be made from refractory or radiation-resistive glasses and employed to probe environments containing corrosive...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 3/27/2024Extended C+L-Band GrismsCoherent’s family of aberration-correcting, high-efficiency grisms and transmission gratings encompass the entire extended C+L band in a single optic for the construction of compact network...BioPhotonics Mar/Apr 2024 IssueBragg Grating Notch FiltersThe WSF series from TeraXion comprises all-fiber band-stop (notch) filters that are used to selectively attenuate or block a wavelength or a range of wavelengths while allowing others to pass...Promoted Content September 2022 IssueBest-in-Class Spectroscopy is Just a Grating AwayThe grating used in a spectrometer design plays a defining role in its performance.
