Abstract: Provided is a thermal mechanical diffusion system and method. In accordance with the present invention, one end of a fiber under tension is vibrated while a portion of the fiber is heated. A push-pull action of one end of the fiber forces increased (or rapid) diffusion of dopants in the portion of the fiber that is in a heat zone, which receives the heat. By controlling the amplitude and frequency of the vibration, a diffusion profile of one or more fibers can be dictated with precision. Heat sources having narrower thermal profiles can enable greater precision in dictating the diffusion profile. As an example, this can be particularly useful for creating a diffusion taper within a fiber to be spliced, where the taper is a result of thermal expansion of the fiber core. Diffusion can occur much more rapidly than is typical.

A method is provided to determine the correct rotational orientation of a fiber with non-circular cladding geometry so that the on screen position of the fiber core may be adjusted to present the flat side of the fiber cladding perpendicular to the imaging axis of the sensor. Once the fiber is clamped into the splicing apparatus multiple images at a series of different known rotational angles are captured. The images are processed to locate key fiber structural features. The relationship between the relevant structures is then processed mathematically to calculate a rotational angle that corresponds to a symmetrical positioning of the core as within the cladding image. The fiber is then rotated to the calculated rotational angle and the splice is completed.

Abstract: A side-hole optical cane for measuring pressure and/or temperature is disclosed. The side-hole cane has a light guiding core containing a sensor and a cladding containing symmetrical side-holes extending substantially parallel to the core. The side-holes cause an asymmetric stress across the core of the sensor creating a birefringent sensor.

The side-hole cane structure self-compensates and is insensitive to temperature variations when used as a pressure sensor, because temperature induces an equal shift in both the first and second wavelengths. Furthermore, the magnitude of these shifts can be monitored to deduce temperature, hence providing the side-hole cane additional temperature sensing capability that is unaffected by pressure.
