Nanolasers [PDF]

open access: yesNanophotonics
As the demand for smaller and more compact lasers increases, the physical dimensions of laser diodes are already at the diffraction limit, which impairs this miniaturization trend and limits direct laser integration into photonic and especially ...

Switchable dual-mode nanolaser: mastering emission and invisibility through phase transition materials [PDF]

open access: yesNanophotonics, 2023
The principle of detailed balance states that objects efficiently emitting radiation at a specific wavelength also efficiently absorb radiation at the same wavelength. This principle presents challenges for the design and performance of photonic devices,

Low-Threshold Nanolaser Based on Hybrid Plasmonic Waveguide Mode Supported by Metallic Grating Waveguide Structure [PDF]

open access: yesNanomaterials, 2021
A high Q-factor of the nanocavity can effectively reduce the threshold of nanolasers. In this paper, a modified nanostructure composed of a silver grating on a low-index dielectric layer (LID) and a high-index dielectric layer (HID) was proposed to ...

Anti-Icing Property of Superhydrophobic Nanostructured Brass via Deposition of Silica Nanoparticles and Nanolaser Treatment [PDF]

open access: yesNanomaterials, 2023
Ice accumulation on brass surfaces can lead to heat transfer inefficiency, equipment degradation, and potential accidents. To address this issue, superhydrophobic surface technology is utilized.

Photonic neuromorphic computing using symmetry-protected zero modes in coupled nanolaser arrays [PDF]

open access: yesNature Communications
Photonic neuromorphic computing has emerged as a promising approach toward energy-efficient artificial neural networks (ANN). Nanolasers, in particular, have become attractive candidates due to their ultra-low power consumption and intrinsic nonlinear ...

On‐Chip Monolithically Integrated Ultraviolet Low‐Threshold Plasmonic Metal‒Semiconductor Heterojunction Nanolasers [PDF]

open access: yesAdvanced Science, 2023
The metal‒semiconductor heterojunction is imperative for the realization of electrically driven nanolasers for chip‐level platforms. Progress in developing such nanolasers has hitherto rarely been realized, however, because of their complexity in ...

Water Harvesting Performance of Modified Nanostructure Aluminum Using Silica Nanoparticles Coating and Laser Processing [PDF]

open access: yesNanomaterials
Dew collection is one of the most efficient water harvesting methods. In this work, we experimentally investigated the effects of modified nanostructured surfaces on water harvesting performance. Aluminum surfaces exhibiting hydrophobic, superhydrophobic,

Few-emitter lasing in single ultra-small nanocavities [PDF]

open access: yesNanophotonics
Lasers are ubiquitous for information storage, processing, communications, sensing, biological research and medical applications. To decrease their energy and materials usage, a key quest is to miniaturise lasers down to nanocavities.

Colloidal-quantum-dot nanolaser oscillating at a bound-state-in-the-continuum with planar surface topography for a high Q-factor [PDF]

open access: yesNanophotonics
Solution-based optical gain materials offer a cost-effective path to coherent light sources. Further, bound states in the continuum (BICs) have garnered great interest owing to their diverging quality (Q) factors.

Large electromagnetic field enhancement in plasmonic nanoellipse for tunable spaser based applications [PDF]

open access: yesPLoS ONE, 2022
We theoretically demonstrated a class of plasmonic coupled elliptical nanostructure for achieving a spaser or a nanolaser with high intensity. The plasmonic ellipse is made up of gold film substrate.
