Abstract
A resonant-filter image sensor includes a pixel array including a plurality of pixels and a microresonator layer above the pixel array. The microresonator layer includes a plurality of microresonators formed of a first material with an extinction coefficient less than 0.02 at a free-space wavelength of five hundred nanometers. Each of the plurality of pixels may have at least one of the plurality of microresonators at least partially thereabove. The resonant-filter image sensor may further include a layer covering the microresonator layer that has a second refractive index less than a first refractive index, the first refractive index being the refractive index of the first material. Each microresonator may be one of a parallelepiped, a cylinder, a spheroid, and a sphere.
