Maximum RF Input Signal on the Electro-Optic Modulator Transmission Boundary Area for Harmonic Distortion Compensation in Analog Radio Over Fiber

Mb/s data transmission over a RF fiber-optic link using a LiNbO3 microdisk modulator

For the first time, we demonstrate data transmission over a radio frequency (RF) fiber-optic link using a LiNbO3 microdisk configured to modulate an optical carrier. Initial experimental results demonstrate high-quality data transmission up to 100 Mb/s on a 8.7 GHz RF carrier. 2002 Elsevier Science Ltd. All rights reserved.

Alternate spintronic analog of the electro-optic modulator

An Alternate Spintronic Analog of the Electro-optic Modulator

There is significant current interest in spintronic devices fashioned after a spin analog of the electro-optic modulator proposed by Datta and Das [Appl. Phys. Lett., 56, 665 (1990)]. In their modulator, the “modulation” of the spin polarized current is carried out by tuning the Rashba spin-orbit interaction with a gate voltage. Here, we propose an analogous modulator where the modulation is ca...

A Full-Duplex, Dual-Polarization 10Gbps Radio over Fiber system with wavelength reuse for upstream signal

This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...

Higher Order Adaptive Filter Based Predistortion for Nonlinear Distortion Compensation of Radio over Fiber Links

 The biggest limitation of Radio over Fiber (ROF) links in a wireless network is its limited dynamic range due to ‘Non Linear Distortions’ (NLD). In this paper a higher order adaptive filter based modeling and predistortion scheme is proposed to compensate this NLD. The filter is adapted from the distortions of vectormodulated symbols, so that no in-depth knowledge of physical link parameters ...
