    摘要: A hollow core fiber having polarization dependent loss is provided. The hollow core fiber embedded in a cellular cladding having a plurality of cells arranged in a nominally regular cellular lattice. A pre-determined number of cells at pre-determined locations within a cellular cladding are substituted by leakage cells that differ in at least one property including a physical or a chemical property, or both. The leakage cells collectively provide a leakage path that may preferably be made polarization sensitive, such that a core mode with a particular polarization state is selectively coupled to the cladding, thereby inducing polarization dependent loss. The leakage cells may be dispersed along a symmetry axis in a radial distance longer than one or more lattice spacing away from the core. The polarization dependent loss may be controlled further by asymmetric core shapes and/or by introducing additional surface features along the core-cladding interface.

    摘要: The present invention relates to a plastic photonic crystal fiber for terahertz wave transmission and a method for the manufacturing thereof. More particularly, the present invention is directed to a plastic photonic crystal fiber that can be easily manufactured and has low loss characteristics to be used as a waveguide of terahertz waves.

    摘要: A sensor and method for surface plasmon resonance sensing, wherein a small variation of the refractive index of an ambient medium results in a large variation of loss of a sensing mode. The surface plasmon resonance sensor comprises an antiguiding waveguide including a core characterized by a refractive index and a reflector surrounding the core. The reflector has an external surface and is characterized by a band gap and a refractive index higher than the refractive index of the core. A coating is deposited on the external surface of the core, the coating defining with the ambient medium a coating/ambient medium interface. In operation, the coating is in contact with the ambient medium, and the antiguiding waveguide is supplied with an electromagnetic radiation to (a) propagate a mode for sensing having an effective refractive index lower than the refractive index of the core and higher than a refractive index of an ambient medium and (b) produce surface plasmons at the coating/ambient medium interface. The mode for sensing is phase-matched with the surface plasmons at a wavelength within the band gap and a variation of the refractive index of the ambient medium results in a variation of loss of the sensing mode to detect a characteristic of the ambient medium.
