Opto-Mechanical Response of a Suspended-Slab-Core Optical Fiber

Abstract

In this paper we report the numerical evaluation of the opto-mechanical response of a microstructured optical fiber design when submitted to hydrostatic pressure. The fiber was built in silica and is composed of two large holes surrounding a wide thin flat region (suspended-slab-core) that is able to support optical propagating modes. A full-vector finite element program was used to the stress-optical analysis. The opto-mechanical sensitivity of such fiber was evaluated under two schemes of applied hydrostatic pressure.
