Abstract
This work theoretically demonstrates that the ultimate detectivities in interband cascade infrared photodetectors (ICIPs) with identical discrete absorbers are the same as that in a single-absorber detector in the limit of perfect collection, but higher than that in the single-stage detector with a finite diffusion length. Detailed derivations and calculations, along with relevant discussion, are provided to show how ICIPs are optimized for maximizing the detectivity and to understand their underlying physics. ICIPs with identical discrete absorbers are of more significance for practical applications such as those that require high-speed response or circumventing the diffusion length limitation.
