Abstract

In this paper we demonstrate that a positive change in refractive index can be induced by UV radiation in bulk Pyrex, an inexpensive, commercially available glass that is not specifically designed to be photosensitive. We describe the fabrication of channel waveguides in Pyrex by direct UV writing and show that a potassium-ion exchanged layer can be used to host single mode waveguides. The change in refractive index due to the UV writing is found to be 2x10−3.
