Witryna28 lip 2014 · ZnSe has a high refractive index (n~ 2.45) and low optical loss (< 0.1/cm) from 0.8 to 12 um. Therefore ZnSe immersion gratings can enable high-resolution … WitrynaThe gratings produced under this program accommodate beams up to 25 mm in diameter (grating areas to 55 mm×75 mm). Several devices are complete with …
Witryna1 wrz 2012 · Abstract. Achieving high reflectivity from an immersed grating facet can be challenging in the near infrared. The reflectivity of metallic coatings in common use, … WitrynaHere, we present a novel method to fabricate long period gratings using standard single mode optical fibers (SMF). These optical devices were fabricated in a three-step process, which consisted of etching the SMF, then coating it with a thin-film and, the final step, which involved removing sections of the coating periodically by laser ablation. Tin …
