Abstract

A wavelength cross-connect switch (WXC) is proposed and demonstrated. The cross-connect optics have orthogonal imaging systems that operate differently in the switching and spectral planes. The switching plane has 2f Fourier optics with a Rayleigh length. On the other hand, the spectral plane has 4f imaging optics. Two types of switching engines, microelectromechanical system (MEMS) mirrors and liquid crystal on silicon (LCOS), are applied for the same cross-connect optics. The 5×5 WXC with MEMS mirrors has a 100 GHz channel spacing, which is compatible with the International Telecommunication Union (ITU) grid. On the other hand, the WXC with LCOS has a variable channel spacing. The characteristics of two types of WXC are compared. In addition, the port count, which is one of the important parameters, is discussed.
