Grating-Induced Vortices in Photonic Crystal Fiber: a pathway to ultra-high temperature sensing

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate vortex generation in a PCF, enabled by a micro-bend grating produced by structural deformations alone. The grating-resonance is stable at temperatures exceeding 1000 C, yielding a platform for realizing ultra-high-temperature sensors.
