Photonic crystal waveguides as sources of counterpropagating factorizable biphoton states.

Summary of "Photonic crystal waveguides as sources of counterpropagating factorizable biphoton states."

We demonstrate numerically that photonic crystal slab waveguides can generate spectrally unentangled biphoton states, highly desired for heralding of single photons. We achieve this by modally phase matching a counterpropagating spontaneous parametric down-conversion process, in a fully integrated scheme and without the need for periodic poling. Such a configuration is an ideal integrated source of heralded single photons, as it spatially separates the photons of a pair at the source without any extra components, while allowing for generation of spectrally narrow photons on a very short length scale.

Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks.

Water pollution from a variety of diffuse sources carried over or through the ground and into water sources such as LAKES; RIVERS; WETLANDS; coastal waters; and GROUNDWATER. Such diffuse sources include roadways and parking lots (GASOLINE; HEAVY METALS; and motor oil), lawns or agricultural land (excess FERTILIZERS, livestock excrement, and PESTICIDES), landfill seepage, and construction sites (chemicals and trash used in construction processes).
