abstract:
The invention relates to an optical device. The optical device comprises a
waveguide core and a nanocomposite material optically coupled to the
waveguide core. The nanocomposite material includes a plurality of
quantum dots. The nanocomposite material has a nonlinear index of
refraction .gamma. that is at least 10.sup.-9 cm.sup.2/W when irradiated
with an activation light having a wavelength .lamda. between
approximately 3.times.10.sup.-5 cm and 2.times.10.sup.-4 cm.
