Long refractive index changes induced in Ag+ ion-exchanged Er-doped phosphate glass using 248nm excimer laser radiation

Pissadakis, Stavros, Ikiades, Aris, Hua, Ping, Sheridan, Anna K. and Wilkinson, James S. (2004) Long refractive index changes induced in Ag+ ion-exchanged Er-doped phosphate glass using 248nm excimer laser radiation At 7th ESG Conference on Glass Science and Technology. 25 - 28 Apr 2004.

Record type: Conference or Workshop Item (Paper)


Er-doped phosphate glasses are excellent host materials for the fabrication of high-gain waveguide and fibre lasers and amplifiers emitting in the 1.55µm telecommunication window. The photosensitivity of those glasses under intense UV radiation may be of great significance, since diffraction gratings and waveguide structures may be inscribed in such glasses, leading to the development of functional photonic devices. The photosensitivity of a commercial phosphate glass (Schott IOG-1), which is doped with Er ions towards the areas of high energy densities. Such observation is also supported by scanning electron microscopy (SEM) scans of the inscribed gratings, where shallow relief structures of few nanometer height are formed in the bright fringes of the interference pattern; pronouncing significant structural changes due to the UV exposure.
