We report multicasting data from a single orbital angular momentum (OAM) spatial channel onto multiple OAM channels of equally spaced OAM charge numbers. The designed sliced phase patterns for multicasting are loaded on the spatial light modulator. By optimizing the design of the phase pattern, the power of multicasted OAM channels can be equalized. We experimentally demonstrate multicasting five and seven OAM channels from a single-input OAM channel carrying a 100 Gbit/s quadrature phase-shift keying (QPSK) data stream.
我们报告了从单个轨道角动量(OAM)空间信道向多个等间隔 OAM 荷数的 OAM 信道多路广播数据。用于多路广播的设计切片相位模式被加载到空间光调制器上。通过优化相位模式的设计,可以均衡多路广播的 OAM 信道的功率。我们通过实验演示了从单个输入 OAM 信道多路广播五个和七个 OAM 信道,该 OAM 信道承载 100Gbit/s 正交相移键控(QPSK)数据流。
