A silicon photonic–electronic neural network for fibre nonlinearity compensation
Nature Electronics, 2021In optical communication systems, fibre nonlinearity is the major obstacle in increasing the transmission capacity. Typically, digital signal processing techniques and hardware are used to deal with optical communication signals, but increasing speed and

Giant modulation of optical nonlinearity by Floquet engineering
Nature, 2021Strong periodic driving with light offers the potential to coherently manipulate the properties of quantum materials on ultrafast timescales. Recently, strategies have emerged to drastically alter electronic and magnetic properties by optically inducing ...

Van der Waals heterostructure polaritons with moiré-induced nonlinearity
Nature, 2021Controlling matter–light interactions with cavities is of fundamental importance in modern science and technology1. This is exemplified in the strong-coupling regime, where matter–light hybrid modes form, with properties that are controllable by optical ...

This paper analyzes the joint time-series properties of the level and volatility of expected excess stock returns. An unobservable dynamic factor is constructed as a nonlinear proxy for the market risk premia with its first moment and conditional volatility driven by a latent Markov variable.
