Emerging Ta4C3 and Mo2Ti2C3 MXene Nanosheets for Ultrafast Photonics

Advanced Optical Materials, EarlyView.
The present study reports on the ultrafast nonlinear optical (NLO) response and carrier dynamics of two kinds of MXenes, namely Ta4C3Tx and ordered‐phase Mo2Ti2C3Tx. The Mo2Ti2C3Tx MXene is found to exhibit superior NLO response, surpassing all previously studied MXenes and other 2D nanomaterials.

All‐Optically Driven Optofluidic Light Modulator

Advanced Optical Materials, EarlyView.
In this work, an all‐optically driven optofluidic light modulator is developed, based on the optical actuation of waveguided beams by liquid crystals confined in a microfluidic channel. The photovoltaic effect in lithium niobate is employed to control the alignment of the liquid crystal in the microfluidic channel underneath by a light‐induced electric

Few Photons Probe Third‐Order Nonlinear Properties of Nanomaterials in a Plasmonic Nanocavity

Advanced Optical Materials, EarlyView.
It is demonstrated that a few photons probe the nonlinear optical properties of different nanomaterials inside a plasmonic nanocavity. A simple analytical model fits the experimental result, which shows a strong dependence on the nanocavity resonance.

Femtosecond Pulse Shaping with Semiconductor Huygens' Metasurfaces

Advanced Optical Materials, EarlyView.
Spatially variant silicon Huygens' metasurfaces enable femtosecond pulse shaping by tailoring the spectral phase and amplitude of incident pulses. Two key functionalities are demonstrated: temporal stretching and pulse splitting of an input Gaussian pulse.
