A novel approach for a multi-port Wavelength Selective Switch (WSS) is shown in this work. The switching is performed from a series of 8 input fibers to a series of 24 output fibers. This device can be useful in reducing the complexity of optical communication nodes based on conventional switch with only one input fiber

The multi-port switching is based on a spatial separation, of light beams, according to input port and wavelength channel on a dynamic steering device – LCoS (Liquid Crystal on Silicon) SLM (Spatial light modulator).

The LCoS SLM was extensively characterized in order to understand the capabilities and limitations for better system design.

The system design is extensively discussed in this paper and a proof of concept experiment demonstrates that indeed this concept can be realized.
