涡旋光束中信息传输速率的上界

An Upper Bound on the Rate of Information Transfer in Optical Vortex Beams

Matt M Coles

摘要:

被赋予轨道角动量的光,通常被称为光学涡旋光,具有由轨道量子数$l$索引的方位角相位。与光学自旋角动量的两个基态相反,对光学涡旋光束的信息内容的兴趣集中在假设$\lvert{l}\rangle{}$形成可数无限的基态集合上。最近的实验观察,群速度是成反比的$l$提供了一个理论基础的信息传输的实际措施。这封信为这一措施设定了一个上限。

英文摘要:

Light endowed with orbital angular momentum, commonly termed optical vortex light, has an azimuthal phase indexed by the orbital quantum number $l$. In contrast to the two basis states of the optical spin angular momentum, the interest in the information content of optical vortex beams is centred on the assumption that $\lvert{l}\rangle{}$ forms a countably infinite set of basis states. The recent experimental observation that group velocity is inversely proportional to $l$ provides a theoretical basis for a practical measure of information transfer. This Letter sets an upper bound on that measure.
