Vanishing quantum confinement enables bright and thermally excited multi-carrier emission from semiconductor nanocrystals
Tjom Arens, Sander J. W. Vonk, A. Willem Vlasblom +5
Recently, nanocrystals in the regime of vanishing quantum confinement-termed bulk nanocrystals (BNCs)-have demonstrated remarkable optical gain characteristics. While their high-po…
Hot-carrier trapping preserves high quantum yields but limits optical gain in InP-based quantum dots
Sander J. W. Vonk, P. Tim Prins, Tong Wang +10
Indium phosphide is the leading material for commercial applications of colloidal quantum dots. To date, however, the community has failed to achieve successful operation under str…
Single-mode emission by phase-delayed coupling between nano-lasers
T. V. Raziman, Anna Fischer, Riccardo Nori +10
Near-field coupling between nanolasers enables collective high-power lasing but leads to complex spectral reshaping and multimode operation, limiting the emission brightness, spati…
Mode visualisation and control of complex lasers using neural networks
Wai Kit Ng, T. V. Raziman, Dhruv Saxena +7
Understanding the behaviour of complex laser systems is an outstanding challenge, especially in the presence of nonlinear interactions between modes. Hidden features, such as the g…
A silicon photonics waveguide-coupled colloidal quantum dot photodiode sensitive beyond 1.6 um
Chao Pang, Yu-Hao Deng, Ezat Kheradmand +6
Silicon photonics faces a persistent challenge in extending photodetection capabilities beyond the 1.6 um wavelength range, primarily due to the lack of appropriate epitaxial mater…
A Roadmap to Decipher Ultrafast Photophysics in Two-Dimensional Nanomaterials
Pieter Schiettecatte, Zeger Hens, Pieter Geiregat
Atomically thin two-dimensional (2D) semiconductors are extensively investigated for opto-electronic applications that require strong light-matter interactions. In view of such app…
Generating Triplets in Organic Semiconductor Tetracene upon Photoexcitation of Transition Metal Dichalcogenide ReS
Sourav Maiti, Deepika Poonia, Pieter Schiettecatte +4
We studied the dynamics of transfer of photoexcited electronic states in a bilayer of the two-dimensional transition metal dichalcogenide ReS and tetracene, with the aim to pro…
Unraveling the Photophysics of Liquid-Phase Exfoliated Two-Dimensional ReS2 Nanoflakes
Pieter Schiettecatte, Deepika Poonia, Ivo Tanghe +6
Few-layered transition metal dichalcogenides (TMDs) are increasingly popular materials for optoelectronics and catalysis. Amongst the various types of TMDs available today, rhenium…
On-Chip Integrated Quantum-Dot Silicon-Nitride Microdisk Lasers
Weiqiang Xie, Thilo Stöferle, Gabriele Rainò +8
Hybrid SiN-QD microlasers coupled to a passive SiN output waveguide with 7μm diameter and record low threshold density of 27 μJ cm-2 are demonstrated. A new design and unique proce…
Nearly Blinking-Free, High-Purity Single-Photon Emission by Colloidal InP/ZnSe Quantum Dots
Vigneshwaran Chandrasekaran, Mickaël D. Tessier, Dorian Dupont +3
Colloidal core/shell InP/ZnSe quantum dots (QDs), recently produced using an improved synthesis method, have a great potential in life-science applications as well as in integrated…
