Blue lasers, lasers that emit a light beam with a wavelength between 400 nm and 500 nm, are key components of various technologies, ranging from high-resolution displays to printers, medical imaging ...
A new study in Nature Physics demonstrates a novel method for generating quantum entanglement using a quantum dot, which violates the Bell inequality. This method uses ultra-low power levels and could ...
Quantum dots are attractive because of their tunability. Their size directly controls how they absorb and emit light, giving researchers a single material that can be adapted for different optical, ...
A team of researchers from China reports a significant advance that could finally overcome this bottleneck. Writing in Light: Science & Applications ("Tunable quantum dots in monolithic Fabry-Perot ...
Luminescence refers to the result of a process in which an object absorbs light at one wavelength and then re-emits it at another wavelength. Through light absorption, electrons in the ground state of ...
This study reveals that low-temperature nucleation and high-temperature growth represent an effective strategy for balancing monomer and ionic ligand supply in the direct synthesis of ions-coordinated ...
Quantum dots (QDs) are semiconducting nanoparticles with distinct optical and electrical properties that fall between bulk materials and discrete molecules. QDs' size-dependent tunability makes them ...
(Nanowerk News) What do motion detectors, self-driving cars, chemical analyzers and satellites have in common? They all contain detectors for infrared (IR) light. At their core and besides readout ...
Optimized quantum dot lasers show resilience to optical feedback, enabling isolator-free silicon photonics for compact, ...
