Towards ultra-thin monolithic imaging systems: introduction of an optic that mimics space (Conference Presentation)

Paper Abstract

Ultra-thin metalenses promise to miniaturize imaging systems. However, all lenses require an additional propagation length to allow for light to form an image on a detector. We show that by operating directly on the Fourier components of a complex light field, one may develop an optical element that acts to “propagate” light for a distance that is longer than its physically occupied space. We experimentally demonstrate this effect using a 30-mm-long calcite crystal, mimicking an additional 3.5 mm of free-space propagation while preserving the magnification. This work represents an essential step in the miniaturization of all electro-optical systems.
