    Abstract: A method and device for pressure sensing using an optical fiber having a core, a cladding and a Bragg grating imparted in the core for at least partially reflecting an optical signal at a characteristic wavelength. The cladding has two variation regions located on opposite sides of the Bragg grating to allow attachment mechanisms to be disposed against the optical fiber. The attachment mechanisms are mounted to a pressure sensitive structure so as to allow the characteristic wavelength to change according to pressure in an environment. In particular, the variation region has a diameter different from the cladding diameter, and the attachment mechanism comprises a ferrule including a front portion having a profile substantially corresponding to at least a portion of the diameter of the variation region and a butting mechanism which holds the ferrule against the optical fiber.

    Abstract: A large diameter waveguide is provided having a diameter of at least about 0.3 millimeters, and an outer cladding with an inner core with a long period grating included therein. The long period grating either couples forward propagating cores modes to forward propagating cladding modes of one optical signal travelling in one direction in the large diameter waveguide, or couples forward propagating cladding modes to forward propagating cores modes of another optical signal travelling in another direction in the large diameter waveguide. The long period grating has an optical parameter that changes in response to an application of a compressive force on the optical waveguide. The outer cladding may also have the long period grating written therein. The long period grating has concatenated periodic or aperiodic gratings. The optical waveguide may be shaped like a dogbone structure having wider outer sections and a narrower central section inbetween. The long period grating is written in the narrower central section of the dogbone structure. The large diameter waveguide may be used in devices such as a tunable bandpass filter, connector or collimator.

    Abstract: A method and device for tuning an optical device including an optical fiber having a core, a cladding and a Bragg grating imparted in the core to partially reflect an optical signal at a reflection wavelength characteristic of the spacing of the Bragg grating. The cladding has two variation regions located on opposite sides of the Bragg grating to allow attachment mechanisms to be disposed against the optical fiber. The attachment mechanisms are mounted to a frame so as to allow the spacing of the Bragg grating to be changed by an actuator which tunes the reflection wavelength. In particular, the variation region has a diameter different from the cladding diameter, and the attachment mechanism comprises a ferrule including a front portion having a profile substantially corresponding to diameter of the variation region and a butting mechanism butting the ferrule against the optical fiber.
