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.

Suppressed Stokes Shifts and Hot Luminescence from Quantum Dots within Plasmonic Nanocavities

Advanced Optical Materials, EarlyView.
This study demonstrates the suppression of the Stokes shift in lead sulfide quantum dots through integration with plasmonic nanocavities. By enhancing spontaneous emission and altering exciton relaxation pathways, this approach enables direct band‐edge emission with improved radiative efficiency, highlighting the powerful role of nanophotonic ...

Demonstration of a Graphene Adjustable‐Barriers Phototransistor with Tunable Ultra‐High Responsivity

Advanced Optical Materials, EarlyView.
A novel graphene‐based phototransistor with a tunable ultra‐high responsivity of 1.7 x 107 AW−1 has been demonstrated. Due to the selected material combination of amorphous silicon, graphene and n‐germanium, the device is potentially capable of dual‐band detection in the VIS‐IR range.

Graphene as Infrared and Electron Transparent Electrode Applied to the Design of Narrow Bandgap Nanocrystal‐Based Photodiode

Advanced Optical Materials, EarlyView.
The article explores the need for transparent conductive electrode in the context of nanocrystal based infrared photodetectors beyond traditional transparent conductive oxide and metallic grids. Use of such sensor for imaging where the diode is deposited on a read‐out integrated circuit raised the need for top transparent electrode.

Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles

Advanced Optical Materials, EarlyView.
Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.
