摘要

Abstract

Silicon is a common material of choice for semiconductor optics in the infrared spectral range

due to its low cost

well-developed high-volume manufacturing methods

high refractive index

and transparency. It is

however

typically ill-suited for applications in the visible range

due to its large absorption coefficient

especially for green and blue light. Counterintuitively

we demonstrate how ultra-thin crystalline meta-optics enable full-color imaging in the visible range. For this purpose

we employ an inverse design approach

which maximizes the volume under the broadband modulation transfer function of the meta-optics. Beyond that

we demonstrate polarization-multiplexed functionality in the visible. This is particularly important as polarization optics require high index materials

a characteristic often difficult to obtain in the visible.
