Photonic Crystal and Photonic Crystal Fibers Communications [PDF]
EUREKA: Physics and Engineering, 2016 The development of all optical communications could benefit from the index guiding photonic crystal fibers. In communication the photonic crystal fibers could provide many new solutions.

Quadrupole topological photonic crystals [PDF]
Nature Communications, 2020 AbstractQuadrupole topological phases, exhibiting protected boundary states that are themselves topological insulators of lower dimensions, have recently been of great interest. Extensions of these ideas from current tight binding models to continuum theories for realistic materials require the identification of quantized invariants describing the bulk

Spatiotemporal Photonic Crystals
Conference on Lasers and Electro-Optics, 2020 We study photonic systems periodic in both time and space - spatiotemporal photonic crystals, and find that their bandstructure contains both frequency and momentum bandgaps. When the two types of bandgaps coincide, anomalous bandstructure is observed.

Scientific Reports, 2017 AbstractWhen space (time) translation symmetry is spontaneously broken, the space crystal (time crystal) forms; when permittivity and permeability periodically vary with space (time), the photonic crystal (photonic time crystal) forms. We proposed the concept of photonic time crystal and rewritten the Maxwell’s equations.

Photonic crystal microchip laser [PDF]
SPIE Proceedings, 2016 AbstractThe microchip lasers, being very compact and efficient sources of coherent light, suffer from one serious drawback: low spatial quality of the beam strongly reducing the brightness of emitted radiation. Attempts to improve the beam quality, such as pump-beam guiding, external feedback, either strongly reduce the emission power, or drastically ...

Progress in molecular imprinted photonic crystals
Cailiao gongcheng, 2020 Photonic crystal is a kind of ordered material which consists of two or more periodic arranged refractive index materials, and the propagation of light can be controlled by changing its average refractive index or lattice spacing.

Refractive index sensing of gases based on a one-dimensional photonic crystal nanocavity [PDF]
Journal of Sensors and Sensor Systems, 2015 Silicon photonic crystal sensors have become very attractive for various optical sensing applications. Using silicon as a material platform provides the ability to fabricate sensors with other photonic devices on a single chip.
