Claim 0:
1. A lidar system receiver, the receiver comprising:
a photodiode array;
a first wafer;
a plurality of structures integrated on the first wafer to form a metasurface lens, wherein the metasurface lens is configured to focus light pulses received by the lidar system to the photodiode array, and wherein each of the plurality of structures includes at least one dimension that is less than a wavelength of the light pulses; and
wherein the metasurface lens is reflective, the photodiode array is arranged at a first side of the first wafer and the plurality of structures are arranged at a second side of the first wafer opposite the first side, and wherein the plurality of structures are configured to receive the light pulses through the first wafer and reflect the light pulses back through the first wafer to the photodiode array.
