Investigation into multi-pass exposure of 213 nm pulsed UV writing for improved writing response
Investigation into multi-pass exposure of 213 nm pulsed UV writing for improved writing response
We demonstrate an increase in achievable refractive index change of 1.2×10-3 in Ge-doped silica in writing waveguides and gratings using pulsed 213 nm light to deposit the same total fluence over multiple writing passes.

Abstract

We demonstrate an increase in achievable refractive index change of 1.2×10-3 in Ge-doped silica in writing waveguides and gratings using pulsed 213 nm light to deposit the same total fluence over multiple writing passes.
