摘要： An optical fiber includes a cladding 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 optical fiber further includes a core region and a core ring surrounding the core region 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： 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 =0.47λ，核心支持单一模式，并且在大约0.68λ至大约1.05Lambda之间不支持核心半径的表面模式。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： An optical sensor includes a directional coupler comprising at least a first port, a second port, and a third port. The first port is in optical communication with the second port and with the third port such that a first optical signal received by the first port is split into a second optical signal that propagates to the second port and a third optical signal that propagates to the third port. The optical sensor further includes a photonic bandgap fiber having a hollow core and an inner cladding generally surrounding the core. The photonic bandgap fiber is in optical communication with the second port and with the third port. The second optical signal and the third optical signal counterpropagate through the photonic bandgap fiber and return to the third port and the second port, respectively. The photonic bandgap fiber has a phase thermal constant S less than 8 parts-per-million per degree Celsius.
