Researchers at the University of California, Los Angeles (UCLA) have unveiled a new optical technology that enables precise focusing of light—only in one direction. This novel unidirectional focusing ...

Diffractive optics harness microscale surface relief patterns to sculpt optical wavefronts through diffraction, offering compact, lightweight alternatives to conventional refractive lenses. Recent ...

As a promising candidate for the next-generation mobile platform, mixed reality (MR) such as Apple Vision Pro and Meta Quest Pro (both are passthrough virtual reality headsets) has the potential to ...

A paper by CU Boulder Professor Rafael Piestun and PhD candidate Haiyan Wang on diffractive optics was recently published in Optica, the most prestigious journal published by The Optical Society of ...
