Abstract
Apparatus and methods relating to photonic bandgap optical nanostructures are described. Such optical nanostructures may exhibit prohibited photonic bandgaps or allowed photonic bands, and may be used to reject (e.g., block or attenuate) radiation at a first wavelength while allowing transmission of radiation at a second wavelength. Examples of photonic bandgap optical nanostructures includes periodic and quasi-periodic structures, with periodicity or quasi-periodicity in one, two, or three dimensions and structural variations in at least two dimensions. Such photonic bandgap optical nanostructures may be formed in integrated devices that include photodiodes and CMOS circuitry arranged to analyze radiation received by the photodiodes.
