Two colour meta-surface hologram: PlanOpSim design example

Simulated two colour meta-surface hologram

Holograms have always appealed to the imagination of both scientists and the general public. But wide angle and full colour holograms has proven elusive despite many years of research. In this article we explore some of the possibilities for making meta-surface holograms and how they can contribute to this lofty goal.

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 […]

The issue of simulation speed in optimizing meta-surfaces

Why is the calculation time so important? A modern optical design process relies on numerical simulations during nearly all phases of the development cycle. Be it checking the feasibility of a great new idea, optimizing the parameters of a proof-of-concept, identifying risks and tolerances in engineering or combinations of those. Perhaps you’re trying to find […]
