Optical and Thermal Design and Analysis of Phase-Change Metalenses for Active Numerical Aperture Control
The control of a lens’s numerical aperture has potential applications in areas such as photography and imaging, displays, sensing, laser processing and even laser-implosion fusion. In such fields, the ability to control lens properties dynamically is of much interest, and active meta-lenses of vario...
