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 ...

A new type of two-dimensional photonic-crystal (PC) structure called annular PC composed of a dielectric-rod and a circular-air-hole array in a square or triangular lattice such that a dielectric rod is centered within each air hole is studied. The dielectric rods within the air holes greatly modify the dispersion diagram of the photonic crystal ...

Direct observation of topological edge states in silicon photonic crystals: Spin, dispersion, and chiral routing [PDF]
We directly observe the spin, dispersion, and guiding of topological states in photonic crystals. Topological protection in photonics offers new prospects for guiding and manipulating classical and quantum information.
