Design and Fabrication of an All Fiber-Optical Add/Drop Element Based on a Taper-Resonator-Taper Structure

摘要

In this letter, we designed and fabricated an all fiber-optic Add/Drop element based on Taper-Resonator-Taper (TRT) structure, assembling it with V-shaped grooves. We proposed a novel configuration composed of two microspheres and three taper fibers . We can cascade this kind of TRT structure, it will be potentially used as multi-wavelengths Optical Add/Drop Multiplexer and Wavelength Division Multiplexer/Demultiplexer.
