Abstract

We investigate the phase matching conditions and sensitivities of higher order metal jacketed long period gratings (LPGs). These higher order modes have been previously demonstrated to have flatter, and therefore more sensitive, phase matching conditions leading up to the phase matching turning point. We demonstrate this increased sensitivity as applied to a Pd jacketed LPG hydrogen sensor illustrating an improvement in both the refractive index and temperature sensitivity (of the 17th order mode) of an order of magnitude over the lower order (1st-9th) modes.
