Paper Abstract

The proposed one-dimensional photonic crystal waveguide structure can be optimized in three steps as outlined below. At first the imaginary part of the Bloch wavevector inside the 1D PC can be made maximum so that the evanescent light field decays most rapidly and thus the confinement factor of a guided mode becomes maximized when the waveguide is completed. This condition uniquely defines the thickness of two layers in 1D PC. Secondly, the omnidirectional mirror condition can be further enforced for the 1D PC to achieve complete inhibition of light escape in the vertical direction. This can be done by ensuring that for a given frequency the point, (ω, ωn0/c), on TM lightline falls in the forbidden bandgap. Lastly, the thickness of the centerguiding layer can be uniquely determined for given frequency and propagation constant, considering structural symmetry and phase matching condition between lights outgoing from and incoming to the guiding layer.
