Researchers from 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.

Deformation in thin membrane can be measured using simple method

By combining a compressive sensing algorithm with a digital holographic microscope, Prof. Shih-Chi CHEN of the Department of Mechanical and Automation Engineering, Faculty of Engineering, The Chinese University of Hong Kong (CUHK) and his research team have developed a high-speed imaging method. The new approach is able to produce two-photon microscopy images of a 3D sample in one second, which is at a speed three to five times that of the conventional point-scanning method. The research result has been published in the journal Optics Letters recently.
