Single-mode fused biconical taper fibre coupler

Introduction

In many single-mode optical fibre sensors, in particular those based on fibre interferometers, a single-mode 4-port directional coupler is needed to transfer light from one fibre to another. Although the coupling can be achieved with discrete components, a more stable and robust system with a lower insertion loss can be obtained if a fibre coupler is used.
