In this work, we experimentally demonstrate a bi-directional transmission link using light emitting diode (LED) visible light communication (VLC) for both downlink and uplink paths. Time-division-duplex (TDD) is proposed and demonstrated to significantly eliminate the reflection interference in VLC. A free space bi-directional transmission of 2 m using simple on-off keying (OOK) modulation with...

The wave-particle duality of light was verified by multi and single photon interference both through Young’s double slit and Mach-Zehnder interferometer. In these two sets of experiments, the interference in the single photon level is the same as that at multi photons level with long enough exposure time. In the Mach-Zehnder interferometer, the “whichpath” information can be identified by measu...

Light beams carrying orbital angular momentum are key resources in modern photonics. In many applications, the ability to measure the complex spectrum of structured light beams in terms of these fundamental modes is crucial. Here we propose and experimentally validate a simple method that achieves this goal by digital analysis of the interference pattern formed by the light beam and a reference...
