The diffraction of light is a ubiquitous phenomenon in nature where waves spread out as they propagate. This spreading of light beams during propagation limits the efficient transmission of energy and ...

Researchers at Tsinghua University developed the Optical Feature Extraction Engine (OFE2), an optical engine that processes data at 12.5 GHz using light rather than electricity. Its integrated ...

When laser energy is deposited in a target, numerous complex processes take place too rapidly to observe visually. To study and adapt such processes, researchers often use computer modeling. However, ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

A research group led by Assistant Professor Takafumi Tomita and Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed a new microscopy ...

Professor Hyuk-Jun Kwon's team developed ultrahigh-resolution optical doping technology based on microlenses - The technology could potentially be implemented in next-generation 2D semiconductor-based ...

Those who have experienced method development for laser diffraction understand the scenario well: you are dealing with a new type of sample, uncertain about handling a particular detail, and the one ...
