Automatic determination of the remaining cladding thickness of a single-mode fiber half-coupler.
A method for the exact determination of the remaining cladding thickness (h) of a polished single-mode fiber, from the measurement of the throughput attenuation, is shown. Experimental loss variations with h are verified with the theoretical expression of the loss coefficient, which depends on the fiber parameters, source wavelength, and refractive index of the liquid placed over the polished fiber.
