I am reading about this apparatus at Wikipedia: https://en.wikipedia.org/wiki/Magneto-optical_trap And there is the following sentence which I don't understand: "As atoms travel away from the field zero at the center of the trap (halfway between the coils), the spatially-varying Zeeman shift brings an atomic transition into resonance which gives rise to a scattering force that pushes the atoms ba…

Through this collaboration, Canadian photonic quantum computing company Xanadu and ASML will explore lithography-enabled process approaches for improved patterning control and lower-loss photonic structures. The post Xanadu, ASML to Advance Lithography for Photonic Quantum Hardware appeared first on Semiconductor Digest .

Kyocera Corporation and the Research Institute of Electrical Communication (RIEC), Tohoku University have developed a new technology for integrating optical isolators onto silicon photonics chips using "laser annealing," a localized, laser-based heat-treatment method. The post Kyocera and Tohoku University Develop Technology to Integrate Optical Isolators Directly onto Silicon Photonics Chips app…

At the 2026 China International Optoelectronic Exposition (CIOE), Luxshare and its lens module unit Luxvisions jointly showcased multiple optical and sensing technologies, including automotive camera modules, robot vision modules for autonomous guided vehicles (AGVs) and autonomous mobile robots (AMRs), as well as tracking modules and waveguide display components for augmented reality (AR), virtu…

Huawei Technologies has unveiled a 7.2-terabit-per-second near-packaged optics (NPO) module for AI data centres, coupling a high-bandwidth product launch with an effort to shape emerging optical-interconnect standards as AI clusters strain the limits of copper connectivity.

In this episode: AI-enhanced imaging produces clearer images, iPronics and Xanadu receive significant funding, and a new optical fiber type shows promise for quantum signal processing.

Understand resolution, magnification, numerical aperture, wavelength, depth of field, and Köhler illumination in optical microscopy with clear, practical examples. The post Microscope Resolution vs Magnification: NA & Light first appeared on .

In laser physics I am told that inverting a two-level system is not possible, since it will become transparent once the inversion reaches 50% and no longer be able to absorb more photons. This makes it impossible to create a laser using two-level systems. However, a two-level system can be described by the equation for the microscopic polarization $p$ and the density of the the upper state $n$ vi…

How do you add an optical isolator to a silicon photonics chip without exposing the entire chip to high temperatures? A laser-based process could solve it. Kyocera and Tohoku University have developed a technology to integrate optical isolators directly onto silicon photonics chips using laser annealing. The method locally heats the material needed to form […]

Alluxa, Inc., a global leader in high-performance optical coatings, filters, and thin-film deposition technologies, has been recognized by NASA as one of the companies that provided critical components for the telescope's Wide Field Instrument (WFI), the observatory's primary science instrument.

ALBUQUERQUE, N.M. -- Within tiny halos of light clinging to a vanishingly thin wisp of optical fiber, scientist Jongmin Lee guides atoms like marbles through a narrow pipe. Rock the fiber and the atoms shift side by side; they just don't fall off. But don't be deceived by the seemingly delicate nature of his experiment. Lee is exploring how to measure motion precisely in rough-and-tumble environm…

Attosecond pulse trains conventionally demand precisely aligned harmonic emissions, a process akin to orchestral tuning before performance. However, newly described ‘attoquants’ bypass this need entirely through intermodal entanglement, generating pulses without phase-locking between harmonics. These quantum states arise from collective atomic behaviour where multiple indistinguishable sources co…

I have been a passenger in a car driving at night in cambodia, I have noticed that the lights from the cars appear to be lines instead of a circular symetric glow. I know my eyes have the condition where some lights have this " line" effect, so to see whether or not its just my eyes I took a picture To my surprise the camera sees what my eyes did, The effect is more complicated that this though,…
