Abstract: A creep-resistant optical fiber attachment includes an optical fiber 10, having a cladding 12 and a core 14, having a variation region 16 (expanded or recessed) of an outer dimension on of the cladding and a structure, such as a ferrule 30, disposed against least a portion of the variation region 16. The fiber 10 is held in tension against the ferrule and the ferrule 30 has a size and shape that mechanically locks the ferrule 30 to the variation 16, thereby holding the fiber 10 in tension against the ferrule 30 with minimal relative movement (or creep) in at least one axail direction between the fiber 10 and the ferrule 30. The ferrule 30 may be attached to or part of a larger structure, such as a housing. The variation 16 and the ferrule 30 may have various different shapes and sizes. There may also be a buffer layer 18 between the cladding 12 and the ferrule 30 to protect the fiber 10 and/or to help secure the ferrule 30 to the fiber 10 to minimize creep.

Abstract: A highly sensitive optical fiber cavity coating removal detector employs an optical fiber 18 having a pair of Bragg gratings 20,30 embedded therein and separated by a section of fiber making up an optical cavity 26. The optical path length of the cavity 26 is sized with the central reflection wavelength of the fiber gratings 20,30 so as to create an optical resonator. The cavity 26 is coated with a material 40 which corrodes or is otherwise removable, such as aluminum. The coating 40 exerts forces 46 radially inward on the cavity 26 so as to cause the refractive index of the cavity and thus its optical path length to change, thereby causing the resonator to come out of resonance. The forces 46 on the cavity 26 are reduced when the coating 40 corrodes, thereby causing the resonator to re-enter resonance. Additionally, the coating causes optical losses to exist due to non-uniform variations in refractive index caused by non-uniform forces from coating irregularities.

Acoustic sensing of a wellbore, pipeline, or other conduit/tube based on DAS may have increased acoustic sensitivity through fiber optic cable design and/or increasing the Rayleigh backscatter property of a fiber's optical core. Some embodiments may utilize a resonant sensor mechanism with a high Q coupled to the DAS device for increased acoustic sensitivity.

Abstract: An optical fiber feedthrough assembly includes a glass plug disposed in a recess of a feedthrough housing.

Abstract: Optical sensors used in harsh environments require a sealed pressure tight passage of an optical waveguide into an interior of the sensor. In one embodiment, a pressure sensor assembly for determining the pressure of a fluid in a harsh environment includes a sensing element suspended within a fluid filled housing. An optical waveguide that provides communication with the sensing element couples to a feedthrough assembly, which includes a cane-based optical waveguide forming a glass plug sealingly disposed in the housing. The glass plug provides optical communication between the optical waveguide and the sensing element. A pressure transmitting device can transmit the pressure of the fluid to the fluid within the housing. The assembly can maintain the sensing element in a near zero base strain condition and can protect the sensing element from shock/vibration.
