ABSTRACT
Laser-induced refractive index modification in Ag[sup +] ion exchanged waveguides on glass substrates was observed. Waveguiding effects were measured, and an increase in refractive index of more than 2x10[sup -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. © 2001 American Institute of Physics.
