Abstract

See full text

An optical device comprising an optical hydrogel with select regions that have been irradiated with laser light having a pulse energy from 0.01 nJ to 50 nJ and a wavelength from 600 nm to 900 nm. The irradiated regions are characterized by a positive change in refractive index of from 0.01 to 0.06, and exhibit little or no scattering loss. The optical hydrogel is prepared with a hydrophilic monomer.
