Study on Coupling Coefficient and Fabrication of a Kind of Symmetric Twin-Core Silica Fiber

Abstract:

Article Preview

The coupling coefficient of twin-core fiber is discussed with coupled-mode theory in this paper. It shows that the coupling coefficient is related with the pump wavelength, the core diameter, the distance between the centers of the two cores and the relative refractive index difference. And the parameters of the twin-core fibers can be optimized to satisfy different requirements. Using the theory, the twin-core fibers are fabricated by an improved method. The measurement results have an obvious progress than previous work.
