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 0.7Λ and about 1.05Λ, which suggests that such fibers should exhibit a very low propagation loss. 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.
摘要翻译：核心模式与空芯光子带隙光纤（PBF）中的表面模式的耦合可能导致较大的传播损耗。计算机模拟分析了具有三角孔图案的PBF中的几何形状和表面模式的存在之间的关系，并且识别纤维不支持表面模式（即，仅存在核心模式）的核心特征尺寸（例如，半径）的范围，在带隙的整个波长范围内。特别地，对于孔间距λ和孔半径rho = 0.47Lambda，芯支撑单模并且不支持在约0.7λ和约1.05λ之间的核心半径的表面模式，这表明这种光纤应呈现非常低的传播损失。表面模式的存在可以通过单独研究单独的体模式或光纤的几何形状而不需要对缺陷模式进行全面分析来简单和方便地预测。

摘要： We disclose a new structure that allows the creation of sharp and asymmetric lineshapes in optical microcavity systems. In this structure, the response function can vary from 0% to 100% in a frequency range that is narrower than the full width of the resonance itself. Therefore, an optical switch, based upon this structure, may require far less frequency shift to operate, compared with conventional microcavity-based structures. This method may also be used to improve the sensitivity of optical sensors based upon microcavity structures.

摘要： An electronic transportor that allows for the resonant tunneling of electrons between guided states, such as those found in a quantum wire or a line defect in a solid, and localized states, such as those found in a quantum dot or a point defect in a solid, using lateral coupling. In some embodiments, the transporter allows electrons of different energies to be transported to different ports of associated waveguides. In other embodiments, the transportor allows electrons of different energies to be transported at different phases.

摘要： An optical sensor, a method of configuring an optical sensor, and a method of using an optical sensor are provided. The optical sensor includes an optical waveguide having a length and a laser source optically coupled to the waveguide. The laser source has a coherence length. Light from the source is transmitted to the waveguide as a first signal propagating along the waveguide in a first direction and a second signal propagating along the waveguide in a second direction opposite to the first direction. The optical paths of the first signal and the second signal are substantially reciprocal with one another and the first signal and the second signal are combined together after propagating through the waveguide to generate a third signal. The coherence length is greater than 1 meter or is in a range between 200 microns and 10 centimeters.
