Title: SQUARE-HOLE SQUARE-LATTICE PHOTONIC CRYSTAL LOW REFRACTIVE INDEX TWIN COMPENSATION SCATTERING COLUMNS ORTHOGONAL WAVEGUIDE
Abstract:
A square-hole square-lattice photonic crystal orthogonal waveguide having low refractive index twin compensation scattering columns, being a photonic crystal consisting of a low refractive-index first medium column in a high refractive-index background medium arranged in a square crystal lattice, there being removed from said photonic crystal one row and one column of the low refractive-index first medium so as to form an orthogonal waveguide; columns of a second and a third low refractive-index medium are configured at two turning points respectively of said orthogonal waveguide; said second and third medium columns are compensation scattering columns, and said second and third medium compensation scattering columns are low refractive-index medium columns or air holes respectively; the first medium column is a low refractive-index medium square column or square air hole. The structure of the present orthogonal waveguide features very low reflectivity and an extremely high rate of data transmission, and facilitates integration of large scale light paths, thus affording wider space for application of photonic crystals.
