Abstract

We demonstrate a multicasting operation in a wavelength selective switch composed of a liquid crystal on silicon (LCOS) and a multi-layered arrayed waveguide grating (AWG). By modulating the wavefront of an input light into a holographic shape with the LCOS, the input light is equally divided into six output beams. Measured power deviation is less than 1.61 dB and excess loss is less than 2.09 dB.
