Simultaneous Existence of Phononic and Photonic Band Gaps in Phoxonic Crystal Slabs [PDF]

, 2010
We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the centered square lattice and the boron nitride (BN) lattice with two atoms per unit cell ...

Fabrication of 3D photonic band gap crystals for controlling the emission of light [PDF]

EPJ Web of Conferences
3D photonic band gap crystals can be used to manipulate light, for example to increase the emission of an emitter. An inverse woodpile photonic band gap crystal has been fabricated in silicon by FIB lithography and reactive ion etching.

Characteristics of optical system generating ultra-wide photonic band gap and its potential practicability

Results in Physics, 2023
In this study, we design a one-dimensional periodic ring multi-connected optical waveguide network to solve the problem of obtaining ultra-wide photonic band gaps that are too complex for the photonic band gap width to be tuned.

Tunability and enlargement of omnidirectional transmission frequency range in a photonic heterostructure containing Dirac semimetal

AIP Advances, 2018
In this study, We theoretically realized the enlargement of the photonic crystal band gap by a photonic heterostructure containing Dirac semimetal layer. At the same time, since the dielectric constant of the Dirac semimetal changes with its Fermi level,

Emergence and control of photonic band structure in stacked OLED microcavities

Nature Communications, 2021
Understanding and manipulating the photonic band structure formed in stacked Fabry-Pérot microcavity organic light-emitting diodes (OLEDs) is key to optimizing their performance. Here, through intelligent device design, the authors tune the photonic band

Band gap engineering in simultaneous phononic and photonic crystal slabs [PDF]

, 2010
We discuss the simultaneous existence of phononic and photonic band gaps in two types of phononic crystals slabs, namely periodic arrays of nanoholes in a Si membrane and of Si nanodots on a SiO2 membrane. In the former geometry, we investigate in detail

Photonic band gap fiber accelerator

Physical Review Special Topics. Accelerators and Beams, 2001
There are three requirements in making a traveling wave accelerator: longitudinal electric field, synchronization, and confinement. We present and analyze a conceptually new kind of charged particle accelerator, making use of a photonic band gap lattice ...

Planar Photonic Crystal Nanocavities with Active Quantum Nanostructures [PDF]

, 2004
Extreme photon localization is applicable to constructing building blocks in photonic systems and quantum information systems. A finding fact that photon localization in small space modifies the radiation process was reported in 1944 by Purcell, and ...
