In this paper, a new optical add–drop filter (OADF) based on two-dimensional photonic crystal ring resonator (2D PCRR) is proposed. The filter is designed in two-dimensional photonic crystals (2D PCs) with triangular lattice of silicon rods in air. Using the finite-difference time-domain ...
We propose a two-dimensional photonic crystal that possesses a degenerate ring in the momentum space. The photonic crystal is composed of the parallel-plate metal filled with a periodically arranged square array of metallic cylinders. Opening an air gap breaks the z-inversion symmetry, leading to ...
We analyse the double Dirac cones in two-dimensional photonic crystals with C6 symmetry, which lack the reflection symmetry about six-fold axes of the triangular lattice. The double Dirac cones are constructed by accidental degeneracy of the E1 and E2 modes at the Brillouin zone center, which ...
each modified refractive index area is shaped so that a feedback strength is different with respect to directions of two primitive lattice vectors of the lattice; the two-dimensional photonic crystal has a periodic structure of a supercell, which contains a plurality of lattice points; and the su...
Two-dimensional photonic crystals, in analogy to AB/BA stacking bilayer graphene in electronic system, are studied. Inequivalent valleys in the momentum space for photons can be manipulated by simply engineering diameters of cylinders in a honeycomb lattice. The inequivalent valleys in photonic crystal...
