Paper Abstract

A corrugated long period microfiber grating (C-LPMFG) is fabricated by etching the corrugated LPFG down to tens of micrometers in diameter with corrugated periodic structures made by using imprint lithography. It can be a grating because of the periodic effective index difference caused by the corrugated structures without prestrain. During etching of C-LPMFGs the in-situ monitoring of resonant wavelength shows that the wavelength shift varies rapidly with the etching of fiber. The resonant dips are calculated and have similar trends compared with the experiment data. The C-LPMFG is used as a temperature sensor with sensitivity of -146 pm/°C.
