    Abstract: A sensing element of an infrared detector including a first absorber configured to form a first set of minority carriers upon receipt of an infrared flux, a collector, a first barrier disposed between the first absorber and the collector, a second absorber configured to form a second set of minority carriers upon receipt of the infrared flux, and a second barrier disposed between the second absorber and the collector. In response to a voltage being applied to the collector, the first and second set of minority carriers are collected at the collector.

    Abstract: A unit cell of a focal plane array (FPA) is provided. The unit cell includes a first layer having a first absorption coefficient. The first layer is configured to: sense a first portion of a polarized light of an incident light having a first portion and a second portion, convert the first sensed portion of incident light into a first electrical signal, and pass through a second portion of the incident light. Further, the unit cell includes a second layer having a second absorption coefficient and positioned adjacent to the first layer and configured to receive the second portion of the incident light. The second layer is configured to convert the second portion of the incident light to a second electrical signal. Also, the unit cell includes a readout integrated circuit positioned adjacent to the second layer and configured to receive the first electrical signal and the second electrical signal.
