Abstract:
1. A light field sensor comprising: a) a collection of nanoscale resonator detector elements arranged in a layer; and b) a collection of dielectric microlenses arranged in a layer; wherein each microlens of the dielectric microlenses has a refractive index and size selected such that the microlens focuses incident light at an operational wavelength into a beam having a full-width-half-maximum intensity beam waist of less than one half of the operational wavelength when measured adjacent to the microlens; wherein each element of the nanoscale resonator detector elements encloses a volume of at least that enclosed by the full-width-half-maximum intensity beam waist of the beam focused by a microlens onto the nanoscale resonator detector element; wherein each element of the nanoscale resonator detector elements has a total external leakage rate to adjacent detector elements that does not exceed an intrinsic leakage rate of the element due to absorption.
