Tapered Optical Fiber Couplers Fabricated by Droplet-Based Chemical Etching

This paper presents a fabrication method for 2 × 2 twisted fiber-optic directional couplers based on biconical low-loss tapered optical fibers using a two-step wet-etching technique with hydrofluoric acid-based droplets and surface tension-driven flows. The droplet-based wet etching of op...
