Design example: a polarization splitting meta-lens for 1550nm

An attractive feature of meta-surfaces is the ability to encode different functionalities for different incident light, for example wavelength or polarization selective behaviour. This can be achieved by selecting and placing meta-atoms which have simultaneous but different effects for different incident light beams. In this example such a multi-functional meta-surface will be designed. The goal […]

What are metasurfaces good for? A look at beamshaping applications.

The development of optics and photonics technology in areas such as sensing, telecom and display is on a constant quest for increasingly more compact and more performant assemblies. This article provides an overview of the various ways in which ultra-thin metasurfaces can be used to design compact beamshaping in various optical applications.  The advantages of […]
