Abstract
An image sensor for recording incident radiation may include a first layer for filtering the incident radiation by attenuating incident radiation with a frequency below a cutoff frequency and a second light-sensitive layer for absorbing radiation passing through the first layer. The first layer may precede the second light-sensitive layer in a direction of propagation of the incident radiation and the first layer includes at least one aperture passing through the first layer to the second light-sensitive layer for propagating radiation therethrough. The cross sectional size of the at least one aperture may be configured to provide a cutoff frequency so that incident radiation with a frequency below the cutoff frequency is attenuated inside the at least one aperture and incident radiation with a frequency above the cutoff frequency propagates through the at least one aperture.
