Abstract

We show that a dual-core fiber can function as a wavelength selector for applications in Dense WDM systems. The fiber consists of an Erbium-doped core and an undoped core. The principle of operation relies on the large nonlinear effect of the Er-doped core when it is pumped by a 980nm laser diode. The selection of wavelength is achieved by adjusting the pump power launched into the doped core. Wavelengths with spacing of 1nm can be selected with crosstalks as low as 35dB.
