Spatiotemporal Photonic Crystals
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.

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]
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 ...

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

Progress in molecular imprinted photonic crystals
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.
