We discuss a novel type of surface soliton-aberrated surface soliton-appearance in a nonlinear one dimensional photonic crystal and a possibility of this surface soliton formation in two dimensional photonic crystal. An aberrated surface soliton possesses a nonlinear distribution of the wavefront. We show that, in one dimensional photonic crystal, the surface soliton is formed at the photonic c...

in this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. in designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. the initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...

The guided modes lying in the upper gap-edge band in the photonic band structure of photonic crystals have negative values of refractive index. This feature generates many interesting optical phenomena, and some spectacular photonic devices such as focusing slabs have been developed. We report the design of a photonic-crystal, planoconcave lens for focusing incident parallel light, and theoreti...

Introduction: PBSA Project (http://www.pbsafp7.eu) addresses the topic of the EU Framework Programme 7: Bringing terrestrial SME research into the space domain [1]. The project focuses on the development of photonic‐based biosensor technology [2] for biochemical applications into the space domain. Two main fields of application have been identified: biomonitoring human spatial installations, su...

In this paper, a photonic crystal waveguide with point defects and lattice constant perturbations of +5%, -5% are being investigated. Firstly waveguide structures with constant and specific parameters are being studied and photonic band gap diagrams for TE/TM modes are depicted; then pulse propagation in the frequencies available in the band gap are shown. After that, effects of parameters like...

First, we will discuss the limitations and difficulties of MPλS, and we will address that the photonic packet switching will be an ultimate solution to solve the problems of MPλS. Next, we will focus on the OC-based photonic packet switching. The advantages of OC-based photonic packet switching include ultrafast photonic label processing capability, optical buffering using WDM fiber delay lines...

This paper presents a theoretical optical data pathway model. The goal is to evaluate the physics behind photonic crystal/photon relationships and to develop a theoretical model for photonic crystal implementation into VLSI system design. This paper will begin with the exploration of the fundamentals of wave propagation in photonic crystals, development of an optical transmitting device (laser ...

We introduce graded photonic quasicrystals (GPQs) and investigate properties of such structures on the example of Luneburg lens based on a dodecagonal photonic quasicrystal. It is shown that the graded photonic quasicrystal lens has better focusing properties as compared with the graded photonic crystal lens in a frequency range suitable for experimental realization. The proposed graded photoni...

Silicon carbide is evolving as a prominent solid-state platform for the realization of quantum information processing hardware. Angle-etched nanodevices are emerging solution to photonic integration in bulk substrates where color centers best defined. We model triangular cross-section waveguides and crystal cavities using Finite-Difference Time-Domain Eigensolver approaches. analyze optimal cen...

We develop a class of supercell photonic crystals supporting complete photonic bandgaps based on breaking spatial symmetries of the underlying primitive photonic crystal. One member of this class based on a two-dimensional honeycomb structure supports a complete bandgap for an indexcontrast ratio as low as nhigh/nlow = 2.1, making this the first such 2D photonic crystal to support a complete ba...
