Measurement of Thermal Gradients Using Long Period Gratings at Different Levels of Ambient Refractive Indices
Abstract
In this paper, we present the results for thermal gradient measurements using constant period UV written long-period gratings (LPGs) in photosensitive and SMF-28 fibers. We have studied theoretically and experimentally the effect of thermal gradients on the spectrum of LPGs. It has been shown theoretically and confirmed experimentally that thermal gradients lead to changes of the depth of the grating spectrum while changes of the mean …
