Abstract
Devices are made comprising a tin-phosphorous oxyfluoride glass, which has been exposed to light, preferably shorter in wavelength than the absorption edge of the glass, to change the refractive index change of the glass. The glasses can be used to form planar and fiber devices, including core/clad structures for guiding light.
Claims20
A device comprising tin-phosphorous oxyfluoride glass which has been exposed to light for a time sufficient to change the refractive index of the glass.
A method of making a device comprising the steps of exposing a tin-phosphorous oxyfluoride glass to light for a time sufficient to induce a refractive index change in the glass.
