Abstract
There is described an optical waveguide structure exhibiting nonlinear properties, a method of fabricating such, and an optical coupling device made of two of such optical waveguide structures. The optical waveguide structure comprises an optical waveguide portion made of a light transmitting material for supporting a light mode traveling therein. The light transmitting material has an intrinsic nonlinearity parameter suitable for inducing a nonlinearity on the light mode, and the optical waveguide portion having a diameter sized to securely confine the light mode therein and to increase the nonlinearity on the light mode. The optical waveguide structure also has a coating surrounding the optical waveguide portion to mechanically support or to protect the optical waveguide portion from surface damage.
