Fractal Photonic Crystal Waveguides

open access: yes, 2004
We propose a new class of one-dimensional (1D) photonic waveguides: the fractal photonic crystal waveguides (FPCWs). These structures are photonic crystal waveguides (PCWs) etched with fratal distribution of grooves such as Cantor bars.

Observation of Cartesian light propagation through a three-dimensional cavity superlattice in a silicon photonic band gap crystal

open access: yesPhysical Review Research
We experimentally investigate peculiar light propagation inside a three-dimensional (3D) superlattice of resonant cavities that are confined within a 3D photonic band gap.

The Determination of the Sensitivity of Refractive Index Sensors

open access: yesPhotonics
A new approach to determining the sensitivity of refractive index sensors is proposed. It has been shown that relative and absolute sensitivity show different results, and also, for the first time, it is demonstrated that relative sensitivity has ...

Propagation of the Ultra-Short Laser Pulses Through the Helical 1D Photonic Crystal Structure with Twist Defect

open access: yesEPJ Web of Conferences, 2016
The presence of the photonic band-gap is a featured property of the cholesteric liquid crystals (CLC). It can be practically realized for almost any reasonable wavelengths with very high degree of tunability.

A novel approach to salinity monitoring using two dimensional hexagonal photonic crystals

open access: yesScientific Reports
We developed a novel structure by constructing a hexagonal cylindrical configuration within a dielectric host, which showcases a substantial band gap. This was achieved using two-dimensional photonic crystals that possess triangular lattice periodicity ...

Faraday effect in bi-periodic photonic-magnonic crystals

open access: yes, 2017
We present a theoretical investigation of the polarization plane rotation at light transmission - Faraday effect, through one-dimensional multilayered magneto-photonic systems consisting of periodically distributed magnetic and dielectric layers.

Three-periodic 1D photonic crystals based on dielectric oxides SiO2, Al2O3, TiO2, ZrO2: an emerging class of structures with wide possibilities for applied photonics

open access: yesКомпьютерная оптика
One-dimensional three-periodic photonic-crystal (PC) structures based on dielectric nonmagnetic materials (SiO2, Al2O3, TiO2, ZrO2) that form [(ab)N(cd)M]K supercells including “internal” subcells of the (ab)N and (cd)M types are considered.

Asymmetric Band Gaps in Amorphous Photonic Materials

open access: yes2018 IEEE Photonics Conference (IPC), 2018
A Monte Carlo method-based design guideline for 2-D amorphous photonic materials are presented. The parameters affecting band gap are analyzed numerically and experimentally for telecommunication wavelengths. Asymmetric nature of band gap is explained in analogy with solid-state electronics.
