Abstract: In embodiments, an optoelectronic apparatus may include a substrate with a first side and a second side opposite the first side; a photodetector disposed on the first side of the substrate, the photodetector to convert a light signal into an electrical signal; and a dielectric metasurface lens etched into the second side of the substrate, the dielectric metasurface lens to collect incident light and focus it through the substrate onto the photodetector.
