摘要： Multi-spectral filter elements and methods of formation are disclosed. Each multi-spectral filter element may include a plurality of sub-filters that are, in some embodiments, each adapted to respond to electromagnetic radiation within respective ones of a plurality of spectral bands. A method embodiment includes forming an optical cavity layer. Volume of the optical cavity layer can be reduced in at least N−1 number of spatial regions. The reducing may include a number of selective removal steps equal to the binary logarithm function Log2 N. In this example, each spatial region corresponds to a respective one of the plurality sub-filters. The plurality of sub-filters include at least N sub-filters. In particular embodiments, the respective ones of the plurality of spectral bands may be at least partially discrete with respect to each other.

摘要： In a method embodiment, a method includes generating one or more first signals proportional to the position and intensity of photons within a first range of wavelengths and incident on a position sensing pixel of an array of position sensing pixels. The method further includes generating one or more second signals proportional to a number of photons within a second range of wavelengths and incident on an image sensing pixel of an array of image sensing pixels. The array of image sensing pixels is formed monolithically on the array of position sensing pixels.

摘要： A broadband radiation detector includes a first layer having a first type of electrical conductivity type. A second layer has a second type of electrical conductivity type and an energy bandgap responsive to radiation in a first spectral region. A third layer has the second type of electrical conductivity type and an energy bandgap responsive to radiation in a second spectral region comprising longer wavelengths than the wavelengths of the first spectral region. The broadband radiation detector further includes a plurality of internal regions. Each internal region may be disposed at least partially within the third layer and each internal region may include a refractive index that is different from a refractive index of the third layer. The plurality of internal regions may be arranged according to a regularly repeating pattern.
