We propose an ultracompact triplexer based on a shift of the cutoff frequency of the fundamental mode in a planar photonie crystal waveguide (PCW) with a triangular lattice of air holes. The shift is realized by mod...
By using the complex finite element method (FEM) under perfectly matched layer (PML) boundary conditions, dispersion properties of microstructured optical fibres (MOFs) with elliptical air holes are analysed by ...
We investigate the focusing properties of photonic crystal structures with a concavo-concave as the photonic crystal boundary. The photonic crystal is constituted by air holes parallelly distributed in a uniform diele...
We report the results of our investigation on the loss property of a birefringent photonic crystal fibre (PCF) based on a particular periodic arrangement of air-holes and pure silica. The structure of the birefringe...
Deformation of some air holes often occurs during the fabrication process of photonic crystal fibres (PCFs). Effects of the location and size of deformation holes on the properties of actual triangular lattice PCFs ...

In our previous papers we have studied the production of a single hole in the photon number distribution of a field state [Phys. Lett. A 240 (1998) 277;253 (1999) 123]. In this letter we extend the procedure for the c...

We have studied the behavior of two holes in the CuO_(2) plane of cuprate superconductors which is important for making clear the origin of the superconductivity.The interaction between two holes does not show a simpl...
