چکیده

A technique to suppress optical nonlinearities is demonstrated using adaptive optical domain post distortion. The concept, rooted in electrical domain linearization, mitigates optical nonlinearities by generating sidebands that are equal but opposite in phase from the unwanted components. We model and experimentally demonstrate >20 dB extinction in four wave mixing by an adaptive phase controller and computer feedback loop.

Adaptive Post-distortion for Photodetector Linearization

Nonlinearities due to photodetector saturation limit the maximum dynamic range achievable in short fiber optic links. We demonstrate an adaptive method for photodetector linearization using a monolithic CMOS polynomial generator. Improvements of 16 dB and 5.1 dB are achieved in the 2 and 3 order limited dynamic ranges, respectively.

Linearization Technologies for Broadband Radio-Over-Fiber Transmission Systems

Linearization technologies that can be used for linearizing RoF transmission are reviewed. Three main linearization methods, i.e. electrical analog linearization, optical linearization, and electrical digital linearization are presented and compared. Analog linearization can be achieved using analog predistortion circuits, and can be used for suppression of odd order nonlinear distortion compon...

Adaptive Linearization of A Loudspeaker

II. THE ADAPTIVE PRE-DISTORTION SCHEME This paper presents a new and promising application for adaptive nonlinear filters adaptive linearization of a loudspeaker. In a loudspeaker, the nonlinearity in the suspension system produces a significant distortion at low frequencies and the inhomogeneity in the flux density causes a nonlinear distortion at large output signals. These distortions should...

Adaptive asymmetric linearization of radio over fiber links for wireless access

The biggest concern in the use of radio-over-fiber (ROF) links in wireless access is their limited dynamic range due to nonlinear distortion (NLD). In this paper, a higher order adaptive filter based nonlinearity compensation scheme is proposed. Pre-compensation is done for the downlink while post-compensation is done for the uplink to result in asymmetry with respect to complexity. This centra...
