Designing next-generation optical antennas

Phys.org  March 13, 2019 A team of researchers in the US (University of Notre Dame, UT Austin) designed and built optical antennas on an Epsilon-Near-Zero Material (ENZ) material to demonstrate a multimode, nearly monochromatic antenna. They are currently working to incorporate the optical antennas into semiconductor devices in order to improve the interaction between light and semiconductor materials. The technique has potential applications in sensing, imaging, infrared optoelectronics, and thermal emission control…read more. TECHNICAL ARTICLE
