Claim 3:
4. A method of operating a lidar system, the method comprising:
receiving light pulses by a metasurface lens of the lidar system, wherein the metasurface lens includes a plurality of structures arranged in an array on a first wafer of the lidar system;
focusing, by the metasurface lens, the light pulses to a photodiode array of the lidar system, wherein each of the plurality of structures includes at least one dimension that is less than a wavelength of the received light pulses;
determining location of a target using the received detected light pulses; and
wherein the metasurface lens is reflective, and 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 focusing, by the metasurface lens, the light pulses to the photodiode array includes the plurality of structures of the metasurface lens receiving the light pulses through the first wafer and reflecting the light pulses back through the first wafer to the photodiode array.
