Multispectral and polarization-selective detector

A device comprising:

• at least one first feature, wherein the at least one first feature extends substantially perpendicularly from a substrate, the at least one first feature has a first surrounding area, the first feature is operable to selectively absorb at least a first percentage of a first portion of the radiation in the first surrounding area, the wavelengths of the first portion of the radiation are within a first range, and the first portion of the radiation is linearly polarized on a first direction;
• and
• at least one second feature, wherein the at least one second feature extends substantially perpendicularly from the substrate, the at least one second feature has a second surrounding area, the second feature is operable to selectively absorb at least a second percentage of the second portion of the radiation in the second surrounding area, the wavelengths of the second portion of the radiation are within a second range, and the second portion of the radiation is linearly polarized on a second direction,
• wherein the first range is different from the second range,
• wherein the at least one first feature and the at least one second feature are positioned on the substrate such that the first surrounding area and the second surrounding area overlap by at least 50% of the smaller of the first surrounding area and the second surrounding area, and
• wherein the first percentage or the second percentage is at least 50%.

A device comprising:

• at least one first feature extending substantially perpendicularly to a substrate, the at least one first feature configured to selectively absorb a first portion of radiation;
• and
• at least one second feature extending substantially perpendicular to the substrate, the at least one second feature configured to selectively absorb a second portion of the radiation;
• wherein
• the first portion of radiation and the second portion of radiation are different in at least one parameter selected from a range of wavelength or linear polarization of the radiation, and
• the first feature and the second feature are positioned in proximity and configured such that the at least one first feature is operable to substantially absorb the first portion of the radiation in a receiving area of the device, and the at least one second feature is operable to substantially absorb the second portion of the radiation in the receiving area of the device.
