Abstract

We demonstrate the efficient sorter of Bessel beams separating both the azimuthal and radial components. This is based upon the recently reported transformation of angular to transverse momentum states. We separately identify over forty azimuthal and radial components, with a radial spacing of 1588 m(-1), and outline how the device could be used to identify the two spatial dimensions simultaneously.

摘要

我们展示了一种高效的贝塞尔光束分选器，它能分离方位角和径向分量。这是基于最近报道的角动量到横向动量态的转换。我们分别识别出四十多个方位角和径向分量，径向间距为1588米⁻¹，并概述了该装置如何可用于同时识别两个空间维度。
