Abstract

A novel controllable wavelength-selective coupling photonic crystal fiber (PCF) has been proposed. This coupler allows highly accurate control of the filtering wavelength. The different wavelengths can be selected by controlling the bending radius of the fiber. Coupling characteristics of novel controllable wavelength-selective coupling PCF are evaluated by using a vector finite element method and their application to a multiplexer demultiplexer based on the novel coupler is investigated. When the fiber length is 4741μm, the bending radius of PCF couplers for 1.48/1.55μm, 1.3/1.55μm, 0.98/1.55μm, and 0.85/1.55μm is calculated, respectively and the beam propagation analysis is performed. Different from the traditional wavelength-selective coupling PCF, the dual-core PCF is bent and it can realize the separation of multiple wavelengths.
