Title: Fabrication of buried channel waveguides in photosensitive glass using proton beam writing

Abstract

We report our results on the fabrication and characterization of buried, channel optical waveguides in photosensitive Foturan{sup TM} glass using a high energy proton beam. Waveguides were fabricated with varying fluence, and the propagation loss and refractive index change were measured. Near-field mode data measured at 632.8 nm showed that waveguiding could be achieved for all fluences ranging from 10{sup 14} to 10{sup 16} protons/cm{sup 2}. The maximum positive refractive index change of 1.6x10{sup -3} was measured for the highest fluence. The waveguide propagation losses measured using the scattering technique were estimated to be in the range of 8.3-12.9 dB/cm, increasing with proton fluence.
