Nonclassical-light generation in a photonic-band-gap nonlinear planar waveguide

Photonic band-gap properties of a porous silicon periodic planar waveguide

Resonant nonlinear dielectric response in a photonic band gap material.

We study the dielectric response of impurity two-level atoms in a photonic band gap (PBG) to an applied laser field. In this system, the atoms may exchange energy coherently by resonance dipoledipole interaction (RDDI) which is assumed to be strong compared to the spontaneous emission rate. When the applied Rabi frequency exceeds the RDDI energy scale, nonlinear saturation of the absorptive par...

Photonic band-gap waveguide microcavities: Monorails and air bridges

Photonic band-gap monorail and air-bridge waveguide microcavities, operating at the wavelength regime of 1550 nm, are fabricated using GaAs-based compound semiconductors. The fabrication process involves gas-source molecular beam epitaxy, electron-beam lithography, reactive ion etching, and thermal wet oxidation of Al0.93Ga0.07As.The fabrication of the air-bridge microcavity, in particular, als...

Generation and manipulation of nonclassical light using photonic crystals

Photonic crystal cavities can localize light into nanoscale volumes with high quality factors. This permits a strong interaction between light and matter, which is important for the construction of classical light sources with improved properties (e.g., low threshold lasers) and of nonclassical light sources (such as single and entangled photon sources) that are crucial pieces of hardware of qu...

Photonic Band Gap Materials: A Semiconductor for Light

Light in certain engineered dielectric microstructures can flow in a way similar to electrical currents in semiconductor chips. These microstructures represent a new frontier in the field of optics. They provide a foundation for the development of novel micro-photonic devices and the integration of such devices into an optical microchip. Glossary: Photonics: the science of moulding the flow of ...
