High-Capacity Optical Wireless Communication Using Two-Dimensional IR Beam Steering

Abstract: The free-space narrow infrared beams can offer unprecedented data capacity to devices individually, as they can provide non-shared connections that have a large link power budget. By means of a fully passive module based on a high port count arrayed waveguide grating router (AWGR), many infrared beams can be 2D steered individually using wavelength tuning. By applying the defocusing techniques, a compact beam steering module has been realized. A simultaneous communication at up to 112 Gbit/s PAM-4 per beam has been shown with an 80-ports AWGR, thus offering a total wireless throughput beyond 8.9 Tbit/s. The wireless provisioning of multiple ultrahigh-definition video streams has been demonstrated in a proof-of-concept laboratory setup.

Indoor Optical/Radio Wireless Communication - Demonstration of High-Def Video Streaming using Steerable Infrared Beams

Abstract: A hybrid wireless indoor system has been designed and validated which realizes ultrahigh-capacity transmission downstream by directing narrow infrared beams to mobile devices individually, using an AWGR-based module for wavelength-controlled 2D beam steering. For upstream, 60GHz radio techniques are employed which are also used to localize the devices and enable automatic infrared beam steering by a remotely located central communication controller. In a laboratory demonstrator, automatic mobile device localization and IR beam steering is demonstrated, and the transmission performance of conveying two high-def video streams optical-wirelessly to two users individually is demonstrated.

Recent advances in optical technologies for creating ultra-high capacity wireless indoor networks

Abstract: Optical wireless communication is a powerful alternative in local area networks for wireless radio-based communication. We explored directional infrared beams which each can offer an independent ultra-high capacity communication link. Based on diffractive modules, we designed and validated wavelength-tunable 2D beam steering techniques which readily scale up to beyond hundred beams. 60GHz mm-wave radio modules were deployed for user device localization and upstream communication. We have realized our concept in a laboratory setup and validated it with streaming of multiple 10GbE high-definition video signals.
