First of all, thanks to Rainer for his fantastic post.
Here are some comments from the Dr taylor about the detector (2014):
POET will be the future platform for integrated IR and many other device systems.”
The POET IR device addresses the need of military and industrial clients for uncooled mid-wave infrared (MWIR) and long-wave infrared (LWIR) sensors and cameras – for perimeter security, thermography, medical imaging, automotive forward sensors, and smartphone input applications. It has potential advantages over competitive devices in three aspects:
-
MWIR and LWIR detection in the same pixel.MWIR detection (2-8um) occurs in self-assembled quantum dots with normal incidence light and no diffraction gratings, and uses only the n-type heterointerface within POET. The p-type interface results in LWIR detection (8-12um). By combining both interfaces within POET, MWIR and LWIR detection will be obtained simultaneously in the same pixel.
-
Lower device cooling requirements. Near-room-term temperature operation is another advantage of the POET IR detector, possible because of the lower device dark current.
-
Integrated optoelectronic advantages. The devices provides for the practical integration, for the first time, of the optical detector with the electronic transistor readout and signal-processing circuits. Thus, high-density, single-chip focal-plane arrays are possible using front-side imaging, without resorting to wafer thinning.
