Paper Abstract

We have theoretically investigated the polarization properties of a single-mode photonic crystal fiber (PCF), which is pulsed one-side by CO2 laser resulting in partial air-holes collapse and deformation. The CO2 laser micro-fabrication is a common way in PCF post-processing, which is used widely both in writing fiber gratings on PCFs and making optical components such as PCF polarizers. A series models with different valley depth which is due to the collapsed air-holes have been simulated by using a full-vector finite-element method (FEM) with a perfectly matched layer (PML). The theoretical results show that the deeper valley causes a larger insertion loss, at the same time, leading a larger polarization dependence loss (PDL). This research provides an insight into the side-pulsed PCF as well as a guidance on the experiment of CO2 laser micro-fabrication on PCFs.
