Paper Abstract
We present design, fabrication, and characterization results of high numerical aperture (NA) micro-lenses based on a
high contrast transmitarray platform. The high contrast transmitarray is created by periodic arrangement of amorphous
silicon posts with different diameters on a fused silica substrate. We report near infrared high NA micro-lenses with spot
sizes as small as 0.57λ and focusing efficiencies in excess of 80%. We demonstrate a trade-off relation between NA and
efficiency of high contrast array flat micro-lenses, and attribute it to the spatial discretization of their phase profiles.
