We investigate the scalability and performance of a novel optical wireless data center network (OW-DCN) based on passive diffractive optics and fast tunable transmitters. The proposed OW-DCN architecture consists of two parallel inter- and intra- clu

This paper demonstrates a real-time user tracking and handover mechanism for indoor ultrahigh-speed beam-steered optical-wireless systems implementing a low-cost camera. This allows us to tackle LoS blocking by switching to a secondary beam-steering

We present a wavelength-dependent optical true time delay (TTD) for K-band radio beamformer targeting home-satellite communication. A proof-of-concept of optically-assisted radio beamformer with a TTD bandwidth of 2GHz is experimentally demonstrated.
