Abstract

Absorption Biomedical optical imaging Holography Integrated optics Nonlinear optics Optical pulses Optical refraction Optical waveguides Ultrafast optics Waveguide lasers
Femtosecond writing of refractive-index changes in sapphire is demonstrated by doping the crystal with an appropriate ion (here: Ti/sup 3+/) that reduces the threshold of the process. Passive and active buried channel waveguiding is demonstrated.
