Femtosecond irradiation induced refractive-index changes and channel waveguiding in bulk Ti3+:sapphire
Femtosecond writing of refractive-index changes in sapphire is demonstrated by doping the crystal with an appropriate ion (here: Ti3+) that reduces the threshold of the process. Passive and active buried channel waveguiding is demonstrated.
