| Title: | Optimization of 3-hole-assisted PMMA optical fiber with double cladding for UV-induced FBG fabrication | Authors: | Cheng, KCD Tse, MLV Zhou, G Pun, CFJ Chan, WKE Lu, C Wai, PKA Tam, HY |
Issue Date: | 16-Feb-2009 | Source: | Optics express, 16 Feb. 2009, v. 17, no. 4, p. 2080-2088 | Abstract: | We propose a new hole-assisted polymer optical fiber design to eliminate the influence of dopant diffusion and to increase the UV writing efficiency in fiber Bragg grating inscription. The optical waveguide is formed inside a solid core surrounded by a ring of 3 large air holes in enhanced UV photosensitive PMMA with double-cladding. We determined a map of the single-mode and multi-mode phase transitions using a finite-element–based vectorial optical mode solver. We obtained a wide range of geometrical configuration for the single-transverse-mode (HE11) propagation in the visible. The design is optimized to operate at the minimum optical loss wavelengths of 580 nm and 770 nm. | Keywords: | Fiber Bragg gratings Fiber lasers Integrated optoelectronics Optical materials Phase transitions |
