摘要：
An optical device for use as an optical switch, optical amplifier or optical logic circuit comprises an optical waveguide (11) such as a W profile optical fibre formed from an assembly of optically conductive media having different refractive indices, at least one of which is non-linear, as hereinbefore defined whereby an optical signal with a single mode is guided or not guided along the waveguide in accordance with the intensity of the signal; and coupling means for coupling at least two optical signals into an input end of the waveguide. A Y coupler 12 is coupled with the optical waveguide to couple at least two optical signals into an input end of the waveguide. One of the optical signals may comprise a bias signal.
