摘要: Ultra-thin conductors are employed to generate plasmon fields near the surface of the conductors. Emitters, such as atoms, molecules, quantum dots, or quantum wells, in the plasmon fields can emit and absorb light via transitions that are otherwise forbidden in the absence of the plasmon fields. Applications using these forbidden transitions include spectroscopy, organic light sources, and broadband light generation. For example, in a spectroscopic platform, an emitter is disposed in the plasmon fields to excite electronic transitions that are otherwise unexcitable. In organic light sources, plasmon fields quench excited triplet states, allowing fast singlet decay with the emission of light. In broadband light generation, strong two-plasmon spontaneous emission of emitters near ultrathin conductors is employed to produce a broad spectrum of light.

摘要: Methods and systems are disclosed that enhance the yield and speed of emission and control the spectral and angular emission of light emitted by materials under irradiation by high-energy particles through a process known as scintillation. In each case, a photonic structure (of nano- or micron-scale feature sizes) is integrated with a scintillating material, and the photonic structure enhances the yield or controls the spectrum of the material. Various embodiments of this technology and practical demonstrations are disclosed.

摘要: A principle which enables the generation of macroscopic Fock and sub-Poissonian states is disclosed. Generic components of the system include: an electromagnetic structure (possessing one or more electromagnetic resonances), a nonlinear electromagnetic element (such as a nonlinear crystal near or inside the structure), and a source of light. In one embodiment, stimulated gain is used to create large numbers of photons in a cavity, but with very low photon number noise (uncertainty) in the cavity, and thus acts as a Fock laser. This Fock laser is capable of producing these states due to a very sharp intensity-dependent gain (or loss) that selects a particular photon number. The disclosed system and method are robust against both atomic and optical decoherence. Various examples of the new Fock laser design are also described.
