Mode transition induced enhanced temperature sensitivity in long period waveguide gratings near dispersion turning point
We propose a highly sensitive temperature sensor based on long period grating inscribed high index coated ridge waveguide in which the unique feature of mode transition (MT) phenomenon combined with the high thermo optic coefficient (TOC) polymer ambient elevates the differential thermal dependence...
