Abstract:
1. An optical waveguide structure exhibiting nonlinear properties, comprising: an optical waveguide portion made of a light transmitting material for supporting a light mode traveling therein, the light transmitting material having an intrinsic nonlinearity parameter suitable for inducing a nonlinearity on the light mode, wherein a diameter of the light transmitting material is smaller over the optical waveguide portion than over the remainder of the optical waveguide structure, said diameter being sized to securely confine a single light mode in the optical waveguide portion and to increase a waveguide nonlinear parameter; and a coating surrounding the optical waveguide portion to mechanically support and to protect the optical waveguide portion from surface damage; wherein the optical waveguide portion comprises glass and the coating comprises a polymer exhibiting a refractive index suitable for controlling evanescent interaction of the single light mode with an exterior of the optical waveguide structure.
