Paper Abstract

A two core Gemini fiber structure is described with easily accessible cores and suitable for sensing applications. The cross-section of the fiber consists of independent circular cross-sectioned fibers, connected to each other by a narrow glass bridge. The Gemini fiber is mechanically rigid and thermally stable making it suitable for sensing applications with the advantage of allowing for easier coupling at the input and output extremes. A temperature independent bend sensor based on Bragg gratings in the Gemini fiber is demonstrated.
