Abstract: An isotopically-altered, silica based optical fiber is provided having lower losses, broader bandwidth, and broader Raman gain spectrum characteristics than conventional silica-based fiber. A heavier, less naturally abundant isotope of silicon or oxygen is substituted for a lighter, more naturally abundant isotope to shift the infrared absorption to a slightly longer wavelength. In one embodiment, oxygen-18 is substituted for the much more naturally abundant oxygen-16 at least in the core region of the fiber. The resulting isotopically-altered fiber has a minimum loss of 0.044 dB/km less than conventional fiber, and a bandwidth that is 17 percent broader for a loss range between 0.044-0.034 dB/km. The fiber may be easily manufactured with conventional fiber manufacturing equipment by way of a plasma chemical vapor deposition technique. When a 50 percent substitution of oxygen-18 for oxygen-16 is made in the core region of the fiber, the Raman gain spectrum is substantially broadened.

Abstract: An optical waveguide environmental sensor is provided that is capable of detecting a target gas or liquid in the ambient environment in an advantageously short period of time. The waveguide is preferably in the form of an optical fiber having a cladding that contains a photonic band gap structure which in turn envelopes a light conducting, hollow core portion. The cladding further includes at least one elongated side opening that preferably extends the entire length of the fiber and exposes said hollow core portion to the ambient environment, which provides broad and nearly immediate access of the core portion to gases and liquids in the ambient environment, thereby minimizing sensor response time. The ambient gases or liquids filling the hollow core portion and elongated opening function as a ridge and slab, respectively, of an optical ridge waveguide that effectively supports at least one bound optical mode.

Abstract: A fiber optic waveguide is disclosed. The fiber optic waveguide includes a core region (44), and a moat region (50) surrounding the core region (44). A cladding region (42) surrounds the moat region (50) and the core region (44). The cladding region (42) includes a lattice (56) of column structures disposed within a solid background matrix (48). The diameter of the core region (44) is sized for making contact with the moat region (50) for creating an extended core region (54) at longer wavelengths. The core region (44), the moat region (50), and the cladding region (42) function to produce unique dispersion compensating properties, which include negative dispersion and positive dispersion. The core region (44) may be formed from a high index material and the moat region (50) may be formed from a material having a refractive index lower than the refractive index of the core region (44). The cladding region (42) is formed from a material having a refractive index which is higher than the index of the moat region (50) and lower than the refractive index of core region (44).
