1. A waveguide for conducting light comprising:

  • a substrate;

    a high refractive index waveguiding membrane disposed over the substrate forming an air cavity therebetween, the waveguiding membrane confining the light propagating therein by way of total internal reflection, the waveguiding membrane thickness as measured by the wavelength of light propagating in the waveguiding membrane is less than one wavelength thick;

    a photonic bandgap (PBG) crystal being defined in said waveguiding membrane by a periodic array of holes defined through the waveguiding membrane; and

    an optical cavity being defined in the photonic bandgap (PBG) crystal by means of a defect in the periodicity of the array of holes in said waveguiding membrane, the optical cavity confining light therein, and having a mode volume on the order of one cubic wavelength or less.
