Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles

open access: yesAdvanced 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.

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.

Plasmonic Hot Spots on Topological Insulator Nanotips for Enhancing Light Interaction with MoS2 Atomic Monolayer [invited]

open access: yesAdvanced Photonics Research, EarlyView.
A pair of Sb2Te3 topological insulator (TI) nanotips is fabricated by using the focused ion beam lithography to demonstrate the plasmonic hot spot effect at the visible range. The strong enhancement of electric field can be generated on the TI nanotips due to the plasmonic effect, giving rise to the obvious improvement of photoluminescence emission ...
