Abstract

Temperature sensitivities of D-shaped fibers with specified surface structures such as thin film and periodic grating are investigated. The photo resister overlay can induce the evanescent field coupling of the core mode to the cladding mode in the overlay. The mode coupling can be modified by the overlay structures such as a single layer and periodic grating. The temperature sensitivity of D-shaped fibers with versatile overlay structures is also changed.
