Thin-film photonic crystal LEDs with enhanced directionality [PDF]

open access: yes, 2009
The use of photonic crystals for light extraction from light-emitting diodes (LEDs) gives the possibility to shape the farfield emission pattern. This is of particular interest for étendue-limited LED applications that require a more directional ...

The research on temperature sensing properties of photonic crystal fiber based on Liquid crystal filling

open access: yesMATEC Web of Conferences, 2016
Based on the photonic bandgap-photonic crystal fibers( PBG-PCF) fiber core fills the namitic liquid crystal. By readjusting the temperature to change the refractive index, constitute new liquid fiber-optic temperature sensor. In this paper, we use finite

Design of hexagonal chalcogenide photonic crystal fiber with ultra-flattened dispersion in mid-infrared wavelength spectrum

open access: yesBeni-Suef University Journal of Basic and Applied Sciences, 2022
In the last few decades, silica-based photonic crystal fibers (PCFs) have been the subject of extensive research. Traditional silica-based PCFs, however, experience considerable propagation loss when used beyond 3000 nm.

Photonic Crystal Fibers.

open access: yesThe Review of Laser Engineering, 2002
We describe the fundamentals of two new types of fiber, photonic crystal fiber (PCF) and photonic bandgap fiber (PBF). PCF is fabricated by forming small air holes in the cladding of the fiber rather than doping the fiber core with high-index materials.

Studies of particle and atom manipulation using free space light beams and photonic crystal fibres [PDF]

open access: yes, 2009
Light can exert optical forces on matter. In the macroscopic world these forces are minuscule, but on the microscopic or atomic scale, these forces are large enough to trap and manipulate particles.
