Directional torsion and temperature discrimination based on a multicore fiber with a helical structure
We propose and experimentally demonstrate a directional torsion sensor based on a Mach-Zehnder interferometer formed in a multicore fiber (MCF) with a ~570-μm-long helical structure (HS). The HS was fabricated into the MCF ...
Ultra-sensitive chemical and biological analysis via specialty fibers with built-in microstructured optofluidic channels
All-in-fiber optofluidics is an analytical tool that provides enhanced sensing performance with simplified analyzing system design. Currently, its advance is limited either by complicated liquid manipulation and light ...
