Advancing the performance of one-dimensional photonic crystal/photonic wire micro-cavities in silicon-on-insulator [PDF]
, 2008 We present new results that demonstrate advances in the performance achievable in photonic crystal/photonic wire micro-cavities. In one example, a quality-factor value as high as 147,000 has been achieved experimentally at a useful transmission ...

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

Function photonic crystals [PDF]
Physica E: Low-dimensional Systems and Nanostructures, 2011 In the paper, we present a new kind of function photonic crystals, which refractive index is a function of space position. Unlike conventional PCs, which structure grow from two materials, A and B, with different dielectric constants $ε_{A}$ and $ε_{B}$.

Low insertion loss modulator based on a vertically coupled photonic crystal resonator [PDF]
, 2012 We experimentally demonstrate a simple but more efficient technique to modulate and multiplex multiple WDM channels. Our design is based on a bus waveguide vertically coupled to multiple Photonic Crystal (PhC) resonator, each of which modulates an ...

Electrically injected photonic-crystal nanocavities [PDF]
, 2012 Nano-emitters are the new generation of laser devices. A photonic-crystal cavity, which highly confines light in small volumes, in combination with quantum-dots can enhance the efficiency and lower the threshold of this device.

Fabrication of 3D photonic band gap crystals for controlling the emission of light [PDF]
EPJ Web of Conferences3D 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.

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.
