(a) Patterned, 1D-periodic photonic crystal Si waveguide with period is separated from the substrate by a distance . is the hole radius. (b) Dispersion relation for TM (solid curve) and TE (dashed curve) modes in waveguide with , and . The dark region shows the substrate light cone. The point where the TE/TM mode crosses the light line is indicated by a circle.
The attractive force per length per unit power as a function of period for (a) TM and (b) TE modes at wavelength . One period of the waveguide (wv.) is a cube of side length with a circular air hole of radius . The separation between the suspended waveguide and substrate is 100 nm.
The attractive force per length per unit power as a function of distance for (a) TM and (b) TE modes at wavelength .
