摘要:

提出了一种在集成环形谐振腔中产生和操纵矢量涡旋光束的新方法。我们数值计算表明,一个环形谐振器,与适当的光栅,解决了垂直位移接入波导发射一个复杂的光场。发射的光束具有特定的偏振拓扑结构,因此具有横向强度分布和轨道角动量。我们提出了一个组合的几个同心环谐振器,解决了不同的总线指南,产生任意的轨道角动量量子态,这可能是潜在的用于经典和量子通信。最后,我们证明了数值,该设备作为一个轨道角动量分选机与不同的轨道角动量通道之间的平均串扰为-10 dB。

英文摘要:

A novel method to generate and manipulate vector vortex beams in an integrated, ring resonator based geometry is proposed. We show numerically that a ring resonator, with an appropriate grating, addressed by a vertically displaced access waveguide emits a complex optical field. The emitted beam possesses a specific polarization topology, and consequently a transverse intensity profile and orbital angular momentum. We propose a combination of several concentric ring resonators, addressed with different bus guides, to generate arbitrary orbital angular momentum qudit states, which could potentially be used for classical and quantum communications. Finally, we demonstrate numerically that this device works as an orbital angular momentum sorter with an average cross-talk of -10 dB between different orbital angular momentum channels.
