Abstract

Laser-induced refractive index modification in Ag⁺ ion exchanged waveguides on glass substrates was observed. Waveguiding effects were measured, and an increase in refractive index of more than 2 × 10^-3 was deduced. Refractive index profiles show that the maximum radiation-induced difference is attained 4-5 μm below the surface. Possible mechanisms for the material modification are discussed.
