We introduce recently developed space division multiplexing (SDM)-associated technologies into optical wireless communications (OWC) and propose to use incoherent and low-coherence spatial modes to realize optical broadcasting with reliable performance by mitigating coherent interference. We experimentally demonstrate reconfigurable optical beam steering using a programmable multi-plane light conversion (MPLC)-based mode multiplexer (MMUX) and realize point-to-multi-point optical wireless communications with low-loss up-link optical beam combining and reach extension using multimode fiber (MMF). Both incoherent and low-coherence spatial modes can be generated employing cost-efficient components such as a multimode vertical cavity surface emitting laser (MM-VCSEL) and broadband amplified spontaneous emission (ASE) noise source.

使用非相干和低相干空间模式进行双向光无线通信的光广播

我们将最近开发的空分复用 (SDM) 相关技术引入光无线通信 (OWC),并建议使用非相干和低相干空间模式通过减轻相干干扰来实现性能可靠的光广播。我们使用基于可编程多平面光转换 (MPLC) 的模式多路复用器 (MMUX) 实验证明了可重构光束控制,并通过低损耗上行链路光束组合和范围扩展实现点对多点光无线通信使用多模光纤 (MMF)。非相干和低相干空间模式都可以使用具有成本效益的组件生成,例如多模垂直腔面发射激光器 (MM-VCSEL) 和宽带放大自发发射 (ASE) 噪声源。
