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 theoretical…
Long-period gratings (LPGs) induced in optical fibers show exceptional refractive index (RI) sensitivity and thus they are often applied for label-free biosensing. However, during measurements at c…
This paper presents a theoretical analysis and experimental verification of fine-tuning of the spectral response and refractive index sensitivity of microcavity in-line Mach-Zehnder interferometer …
