Surface plasmon resonance based sensor using one-dimensional photonic crystal
Results in Optics, 2023 A surface plasmon resonance (SPR) based sensor is presented for the optical sensing that employs one-dimensional photonic crystal (1DPC). An interface of a metal and 1DPC is utilized to excite the surface plasmon-polariton (SPP) waves using prism ...

One-dimensional photonic crystal optical limiter
Optics Express, 2003 We explore a new passive optical limiter design using transverse modulation instability in the one-dimensional photonic crystal (PC) using x(3) materials. The performance of PC optical limiters strongly depends on the choice of the materials and the geometry and it improves as the duration of the incident pulse is extended.

Annular one-dimensional photonic crystals for salinity sensing
Scientific Reports, 2023 AbstractThe use of annular one-dimensional (1D) photonic crystals (PCs) for salinity sensing is studied in this research. Annular 1D-PCs provide small and integrated structures that facilitate the creation of portable and miniaturized sensor equipment appropriate for field use.

Trapped atoms in one-dimensional photonic crystals
New Journal of Physics, 2013 We describe one-dimensional photonic crystals that support a guided mode suitable for atom trapping within a unit cell, as well as a second probe mode with strong atom-photon interactions. A new hybrid trap is analyzed that combines optical and Casimir-Polder forces to form stable traps for neutral atoms in dielectric nanostructures. By suitable design

Journal of Theoretical and Applied Physics, 2018 Recently, one-dimensional periodic ternary photonic crystals have shown outstanding properties when compared to one-dimensional periodic binary photonic crystals. In this work, a ternary photonic crystal is proposed as a temperature sensor. The structure

On the relation between the propagation constant of Bloch surface waves and the thickness of the upper layer of a photonic crystal [PDF]
Компьютерная оптика, 2018 We consider the derivation of a dispersion relation of Bloch surface waves supported by interfaces between a semi-infinite one-dimensional photonic crystal and a homogeneous medium.

Straightening of light in a one dimensional dilute photonic crystal [PDF]
Scientific Reports, 2019 AbstractLight transport in a dilute photonic crystal is considered. The analytical expression for the transmission coefficient is derived. Straightening of light under certain conditions in a one-dimensional photonic crystal is predicted. Such behavior is caused by the formation of a localized state in transversal motion.

Active microcavity and coupled cavities in one-dimensional photonic crystal [PDF]
Journal of the European Optical Society-Rapid Publications, 2007 The propagation of light in one-dimensional SiO2-TiO2 coupled cavity photonic crystal is investigated. In particular the potential application in light amplification is proposed considering the small group velocity that characterizes the propagation at ...

One-dimensional photonic crystals with cylindrical geometry
Optics Express, 2014 A one-dimensional photonic crystal (1DPC) consisting of a stack of alternate TiO(2) and Al(2)O(3) layers is deposited on the side wall of a glass rod by Atomic Layer Deposition. The stack is designed to sustain TE-polarized Bloch Surface Waves (BSW) in the visible spectrum at wavelengths shorter than 650 nm.
