Broadband single-mode microfiber coupler for OCT

Broadband single-mode microfiber coupler for OCT
Broadband single-mode microfiber coupler for OCT
We present a bi-conical microfiber coupler (MFC) with a 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 microfiber. As a practical example, single-mode operation over a broad spectral window (400~1700 nm) was demonstrated with a 1.1 µm MFC made from conventional telecom optical fibres.

Abstract

We present a bi-conical microfiber coupler (MFC) with a 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 microfiber. As a practical example, single-mode operation over a broad spectral window (400~1700 nm) was demonstrated with a 1.1 µm MFC made from conventional telecom optical fibres.
