Research of two-dimensional beam steering in LCOS-based wavelength selective switch

The phenomenon of two-dimensional beam steering in liquid crystal on silicon (LCOS) is demonstrated. We propose a novel flexible wavelength selective switch (WSS) using LCOS two-dimensional beam steering. The cross talk of adjacent channel in the WSS is theoretically small, while the measured insert...

Zusammenfassung:	The phenomenon of two-dimensional beam steering in liquid crystal on silicon (LCOS) is demonstrated. We propose a novel flexible wavelength selective switch (WSS) using LCOS two-dimensional beam steering. The cross talk of adjacent channel in the WSS is theoretically small, while the measured insert loss is lower than 15 dB.
