Joint Research | The University of Osaka Announcement: Compact LED Design That Directly Emits Circularly Polarized Light, Potentially Simplifying Optical Devices

Researchers from the ULVAC-University of Osaka Joint Research Laboratory for Future Technology and the University of Osaka have proposed a compact LED design that directly emits circularly polarized light using a nanoscale GaN metasurface integrated onto the device. This design removes the need for bulky optical components traditionally used to create polarized light and could help enable smaller optical systems for applications such as 3D displays, augmented reality, and photonic technologies.
