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

open access: yesAdvanced 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.

Tunable‐Wavelength Broadband Liquid‐State Carbon‐Quantum‐Dot Lasers

open access: yesAdvanced Optical Materials, EarlyView.
This work provides a gain‐induced waveguide structure to achieve programmable mode spacing by coupling liquid‐state lasing of carbon quantum dots to a vertically placed aluminum mirror, enabling an unprecedented transition from random lasing to multimode lasing without cumbersome micromanufacturing, even single‐mode lasing at a wide range from 641 to ...

Mitigating Losses in Hyperbolic Asymptotic Eigenmodes

open access: yesAdvanced Photonics Research, EarlyView.
Herein, hyperbolic asymptotic eigenmodes, high‐k modes aligned with asymptotic directions in hyperbolic metamaterials, are introduced. By tuning permittivity tensors to balance loss compensation (Re(ε∥)/Re(ε⊥)=Im(ε∥)/Im(ε⊥))$\left(\right. \text{Re} \left(\right. \left(\epsilon\right)_{\parallel} \left.\right) / \text{Re} \left(\right.

Programmable Wide‐Spectrum Complex Microcavity Laser Controlled by Liquid Crystal Elastomer Braking Mechanism

open access: yesAdvanced Photonics Research, EarlyView.
A nematic liquid crystal elastomer (LCE) exhibiting dynamic laser oscillation behavior modulated by mechanical stretching and contraction is synthesized. This study investigates the influence of liquid crystal elastomer deformation characteristics on multidimensional complex microcavity laser systems.
