Abstract :
Spectral crosstalk suppressing design of simultaneous two-color HgCdTe medium-wave/long-wave (MW/LW) infrared n-p-p-n detector is carried out, using commercial Technology Computer Aided Design (TCAD) software Apsys. A compositional barrier between two absorption layers is introduced and designed to suppress spectral crosstalk. MW-to-LW crosstalk can be notably suppressed to 2.1% while LW-to-MW crosstalk can be maintained less than 1%.
