TL;DR: This work introduces and demonstrates a metalens with a high NA and high transmission in the visible range, based on crystalline silicon (c-Si), and envision the front-immersion design to be beneficial for achieving ultrahigh-NA metalenses as well as immersion metalens doublets, thereby pushing metasurfaces into practical applications such as high resolution, low-cost confocal microscopy and achromatic lenses.

TL;DR: In this article, a few-layer semiconducting transition metal dichalogenides of molybdenum ditelluride (MoTe2) was used as a gain material in a silicon photonic crystal L3 nanocavity.

TL;DR: The QD emission wavelength is extended to 850-880 nm via highly uniform and symmetric InAs QDs located inside indium-droplet-etching nanoholes and individual QDs are shown to emit nonclassically with clear evidence of photon antibunching.

TL;DR: In this paper, the authors report a unique silicon laser source that employs molybdenum ditelluride (MoTe2) as a gain material in a photonic crystal nanocavity resonator, fabricated in silicon-on-insulator.

TL;DR: This paper systematically investigates the influence of the underlying material, showing the morphological evolution of the nanohole structure as well as symmetric GaAs QDs with an average fine-structure splitting (FSS) of (5.9 ± 1.2) μeV, and indicates how to improve the symmetry of nanoholes to meet the requirements for implementing QDs in entangled photon sources.
