Current optical fibre transmission systems rely on modulation, coding and multiplexing techniques that were originally developed for linear communication channels. However, linear transmission ...

Recently, a sensitivity-enhancement technique for system interrogation using linear controllers and eigenstructure assignment has been extended from linear to nonlinear systems. Nonlinearities have ...

A research team has successfully developed a novel platform for reconfigurable nonlinear optics based on ion-doped ferroelectric nematic liquid crystals (FNLCs). This allows for precise control over ...

Concepts of feedback; open loop and closed loop systems. Feedback in electrical and mechanical systems. Mathematical models of systems and linear approximations. Transfer functions of linear systems, ...

The ability to dynamically control the nonlinear phase in optical systems is crucial. It improves flexibility, adaptability, and functionality across ...

A team of researchers at Nagoya University has discovered something surprising. If you have two tiny vibrating elements, each one barely moving on its own, and you combine them in the right way, their ...

Three 1.8-V, 20-Gbps linear redrivers from Diodes allow equalizer and flat gain adjustments to improve signal integrity in USB4 Gen3, Thunderbolt 4.0, and DisplayPort 2.0 connections. The devices ...

Correlation and Circular convolutions. Concepts of orthogonality and Gramm-Schmidt orthogonalization procedure. Fourier series and Fourier transforms (FT): convergence properties; applications to ...

Setting traffic signals in a signal-controlled street network involves the determination of cycle time, splits of green time, and offsets. Part I of this paper considers the network coordination ...
