We demonstrate reconfigurable orbital angular momentum (OAM) and polarization manipulation of OAM- and polarization-multiplexed 100 Gbit/s quadrature phase shift keying (QPSK) data channels. Each data channel's OAM value and its polarization state can be arbitrarily changed by taking advantage of the unique wavefront profile of OAM beams using liquid crystal on silicon-based spatial light modulators. The manipulation operation introduces a power penalty of <1 dB for 100 Gbit/s QPSK signals.
我们演示了可重构轨道角动量（OAM）和 OAM 和偏振复用的 100Gbit/s 正交相移键控（QPSK）数据通道的偏振操纵。每个数据通道的 OAM 值及其偏振状态都可以通过利用硅基液晶空间光调制器的 OAM 光束的独特波前形状来任意改变。该操作对 100Gbit/s QPSK 信号引入的功率代价小于 1dB。
