Abstract
We discuss the influence of the seams between the liquid crystal pixels on the signals that transmits through the LCoS-based switching node in the elastic optical path network. It is found that the seams will bring repetitions of the signal in time domain. Also, the spacing and amplitudes of these repetitions are determined respectively by the spectral spacing and the shapes of the frequency slots implemented by the liquid crystal pixels. By simulating with an LCoS-based switching node model, we propose a feasible approach to reduce this influence.
