Abstract

We report the use of an optical microwire (OMW) with specifically designed transition region as an efficient tool to filter higher-order modes in multimode waveguides. Higher-order modes are effectively suppressed by controlling the transition taper profile and the diameter of the optical microwire. As a practical example, single-mode operation of a standard telecom optical fiber over a broad spectral window (400 ~ 1700 nm) was demonstrated with a 1 mum OMW.
