FIG. 1.

Multicolor response from a typical DWELL detector. The MWIR and LWIR peaks are probably from transitions from a state in the quantum dot to a state in the well and to the continuum, respectively. (note that data scaled by a factor of 5 for readability).

FIG. 2.

Peak responsivity (V/W) and detectivity for the MWIR (left axis) and LWIR (right axis) for the DWELL FPA at . Irradiance levels for MWIR and LWIR are and , respectively.

Image of FIG. 3.
FIG. 3.

Noise equivalent temperature difference obtained in the MWIR and LWIR bands at . Irradiance levels for MWIR and LWIR are and , respectively.

Image of FIG. 4.
FIG. 4.

Images obtained in the MWIR and LWIR using the two-color DWELL camera installed in a closed cycle temperature controllable Dewar at (better imaging has been observed at ).
