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

Researchers at the University of California, Los Angeles (UCLA) have developed an optical computing framework that performs ...

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 new technical paper titled “Massively parallel and universal approximation of nonlinear functions using diffractive ...

Can light perform millions of calculations at once without extra materials? A new optical system shows how this can be done.

In reality, RF signals are “rectified” at the input of the amplifier by electrostatic discharge (ESD) diodes, input structures, and other non-linear elements contained within the amplifier. In a ...

Design linear discrete-time systems and filters and analyze their behavior. Represent continuous-time signals and linear systems in discrete time, so that such signals can be recovered in continuous ...

The nonlinear Hall signal shows a sharp peak when the first moiré valence band is half-filled (Filling = 0.5 shown in the left figure). The corresponding generation efficiency is at least two orders ...

UCLA researchers demonstrate diffractive optical processors as universal nonlinear function approximators using linear ...
