36 Gb/s Narrowband Photoreceiver for mmWave Analog Radio-Over-Fiber [PDF]

open access: yesJournal 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]

open access: yesJournal 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.
