摘要： Using a realistic plasmonic model, an optically thick electrically conductive film with subwavelength hole or holes therein is shown to always support propagating modes near the surface plasmon frequency, where cross-sectional dimensions of the hole or holes are less than about λ/2nh, λ being the wavelength of the light and nh the refractive index of the dielectric material in the hole or holes. This is the case even when material losses are taken into account. Based on the dispersion analysis, in both a single hole or hole array designs, propagating modes play a dominant role in the transport properties of incident light. These structures exhibit a new region of operation, while featuring a high packing density and diffraction-less behavior. These structures can be used in near-field scanning optical microscopy, in collection and emission modes, for writing data to an optical storage device, as wavelength-selective optical filters, for multispectral imaging of a sample, as photolithography masks for transferring an image to a photoresist-coated substrate, as light emitters, light collectors and light modulators.

摘要： A photonic-bandgap fiber includes a photonic crystal lattice with a material having a first refractive index and a pattern of regions formed therein. Each of the regions has a second refractive index lower than the first refractive index. The photonic-bandgap fiber further includes a core and a core ring surrounding the core and having an inner perimeter, an outer perimeter, and a thickness between the inner perimeter and the outer perimeter. The thickness is sized to reduce the number of ring surface modes supported by the core ring.

摘要： Light pulses can be stopped and stored coherently, with an all-optical process that involves an adiabatic and reversible pulse bandwidth compression occurring entirely in the optical domain. Such a process overcomes the fundamental bandwidth-delay constraint in optics, and can generate arbitrarily small group velocities for light pulses with a given bandwidth, without the use of any coherent or resonant light-matter interactions. This is accomplished only by small refractive index modulations performed at moderate speeds and has applications ranging from quantum communications and computing to coherent all-optical memory devices. A complete time reversal and/or temporal/spectral compression and expansion operation on any electromagnetic field is accomplished using only small refractive index modulations and linear optical elements. This process does not require any nonlinear multi-photon processes such as four-wave mixing and thus can be implemented using on-chip tunable microcavity complexes in photonic crystals. The tuning process requires only small refractive index modulations, and moderate modulation speeds without requiring any high-speed electronic sampling.
摘要翻译：光脉冲可以被停止并相干地存储，其全光学过程涉及完全在光学域中发生的绝热和可逆的脉冲带宽压缩。这种过程克服了光学中的基本带宽延迟约束，并且可以为具有给定带宽的光脉冲产生任意小的组速度，而不使用任何相干或共振的光物质相互作用。这仅通过在中等速度下执行的小折射率调制来实现，并且具有从量子通信和计算到相干全光存储器件的应用。在任何电磁场上的完全时间反转和/或时间/频谱压缩和扩展操作仅使用小的折射率调制和线性光学元件来实现。该过程不需要诸如四波混频的任何非线性多光子过程，因此可以使用光子晶体中的片上可调谐微腔复合体来实现。调谐过程只需要较小的折射率调制和适度的调制速度，而不需要任何高速电子采样。

摘要： Coupling of core modes to surface modes in an air-core photonic-bandgap fiber (PBF) can cause large propagation losses. Computer simulations analyze the relationship between the geometry and the presence of surface modes in PBFs having a triangular hole pattern and identify ranges of core characteristic dimensions (e.g., radii) for which the fiber supports no surface modes (i.e., only core modes are present) over the entire wavelength range of the bandgap. In particular, for a hole spacing Λ and a hole radius ρ=0.47Λ, the core supports a single mode and supports no surface modes for core radii between about 0.68Λ and about 1.05Λ. The existence of surface modes can be predicted simply and expediently by studying either the bulk modes alone or the geometry of the fiber without requiring a full analysis of the defect modes.

摘要： An input light-coupling device comprising a dielectric layer containing a pattern of dielectric contrast distributed in at least two dimensions. The pattern of dielectric contrast, which may or may not be periodic, is designed to facilitate coupling to the dielectric layer of electromagnetic radiation. The electromagnetic radiation may be propagating within a surrounding medium of lower dielectric constant than that of said dielectric layer, input at directions including normal incidence from which light cannot typically couple to the dielectric layer without the presence of the pattern of dielectric contrast. The input light may constitute an optical signal propagating in an optical fiber or in free space. Light that is in-coupled may be directed in as many directions as dictated by the symmetry of the pattern of dielectric contrast. The dielectric layer may contain output waveguides surrounding the input coupling structure. The light coupling structure may be fabricated in a dielectric layer separated from a high-dielectric substrate by a low-dielectric layer to avoid losses of the input signal to the substrate. A mirror comprising either a reflective material or alternating layers of high and low dielectric material may be disposed between the low-dielectric layer and the substrate to enhance the total input coupling to the dielectric layer containing the input coupling structure.
