Hybrid Dielectric-Plasmonic Nanoantenna with Multiresonances for Subwavelength Photon Sources
Pavel A. Dmitriev, Emmanuel Lassalle, Lu Ding +7
The enhancement of the photoluminescence of quantum dots induced by an optical nanoantenna has been studied considerably, but there is still significant interest in optimizing and…
'Meta-atomless' architecture based on an irregular continuous fabric of coupling-tuned identical nanopillars enables highly efficient and achromatic metasurfaces
Hüseyin Bilge Yağcı, Hilmi Volkan Demir
Metasurfaces are subwavelength-thick constructs, consisting of discrete meta-atoms, providing discretized levels of phase accumulation that collectively approximate a designed opti…
Single-mode lasing from a single 7 nm thick monolayer of colloidal quantum wells in a monolithic microcavity
Sina Foroutan-Barenji, Onur Erdem, Savas Delikanli +4
In this work, we report the first account of monolithically-fabricated vertical cavity surface emitting lasers (VCSELs) of densely-packed, orientation-controlled, atomically flat c…
Self-Resonant u-Lasers of Colloidal Quantum Wells Constructed by Direct Deep Patterning
Negar Gheshlaghi, Sina Foroutan-Barenji, Onur Erdem +4
Here, the first account of self-resonant fully-colloidal u-lasers made from colloidal quantum well (CQW) solution is reported. A deep patterning technique is developed to fabricate…
Lasing action in single subwavelength particles supporting supercavity modes
Vasilii Mylnikov, Son Tung Ha, Zhenying Pan +4
On-chip light sources are critical for the realization of fully integrated photonic circuitry. So far, semiconductor miniaturized lasers have been mainly limited to sizes on the or…
Control of LED Emission with Functional Dielectric Metasurfaces
Egor Khaidarov, Zhengtong Liu, Ramon Paniagua-Dominguez +8
The improvement of light-emitting diodes (LEDs) is one of the major goals of optoelectronics and photonics research. While emission rate enhancement is certainly one of the targets…
Sub-single exciton optical gain threshold in colloidal semiconductor quantum wells with gradient alloy shelling
Nima Taghipour, Savas Delikanli, Sushant Shendre +7
Colloidal semiconductor quantum wells have emerged as a promising material platform for use in solution-processable light-generation including colloidal lasers. However, applicatio…
Anomalous Spectral Characteristics of Ultrathin sub-nm Colloidal CdSe Nanoplatelets
Sumanta Bose, Savas Delikanli, Aydan Yeltik +6
We demonstrate high quantum yield broad photoluminescence emission of ultrathin sub-nanometer CdSe nanoplatelets (two-monolayer). They also exhibit polarization-characterized later…
Highly efficient visible colloidal lead-halide perovskite nanocrystal light-emitting diodes
Fei Yan, Jun Xing, Guichuan Xing +11
Lead-halide perovskites have been attracting attention for potential use in solid-state lighting. Following the footsteps of solar cells, the field of perovskite light-emitting dio…
A Metalens with Near-Unity Numerical Aperture
Ramon Paniagua-Dominguez, Ye Feng Yu, Egor Khaidarov +8
The numerical aperture (NA) of a lens determines its ability to focus light and its resolving capability. Having a large NA is a very desirable quality for applications requiring s…
Generalized Theory of Forster-type Nonradiative Energy Transfer in Nanostructures with Mixed Dimensionality
P. L. Hernandez-Martinez, A. O. Govorov, H. V. Demir
Forster-type nonradiative energy transfer (NRET) is widely used, especially utilizing nanostructures in different combinations and configurations. However, the existing well-accept…
