36 Gb/s Narrowband Photoreceiver for mmWave Analog Radio-Over-Fiber [PDF]
Journal of Lightwave Technology, 2020 Migrating toward higher frequencies and densification of the communication cells are two key enablers for increased wireless data rates. To make these trends economically viable, centralized architectures based on radio-over-fiber (RoF) are explored. This article describes the design of a photoreceiver that can be applied at the remote radio head in a ...

Optical Heterodyne Analog Radio-Over-Fiber Link for Millimeter-Wave Wireless Systems [PDF]
Journal of Lightwave Technology, 2021 Optical heterodyne analog radio-over-fiber (A-RoF) links provide an efficient solution for future millimeter wave (mm-wave) wireless systems. The phase noise of the photo-generated mm-wave carrier limits the performance of such links, especially, for the transmission of low subcarrier baud rate multi-carrier signals.

Millimeter-Wave Outphasing using Analog-Radio over Fiber for 5G Physical Layer Infrastructure [PDF]
, 2021 In this paper we propose to combine the concepts of outphasing and analog-radio over fiber. The analog outphasing signals are generated centrally and transported to the remote antenna system over fiber. There, high-performance and highly non-linear power
