Researchers from North Carolina State University and the University of Texas have developed and demonstrated a new approach for designing photonic devices. The advance allows them to control the direction and polarization of light from thin-film LEDs, paving the way for a new generation of virtual reality (VR) and augmented reality (AR) technologies. This is a fundamentally new device architecture for photonic devices, says Franky So, corresponding author of a paper describing the work. And we ve demonstrated that, using our approach, directional and polarized emissions from an organic LED or a perovskite LED without external optical elements can be realized. So is the Walter and Ida Freeman Distinguished Professor of M
