“…1 Figure 1 shows the fraction of incident light absorbed in the four quantum-well stacks versus the angle of linearly polarized incident light. These curves demonstrate that the relative photocurrents from the four quantum-well stacks provide a means to measure the polarization of incident light.…”

In the Advanced Detectors Research Group of the Air Force Research Laboratory's Space Vehicles Directorate, we work to enhance existing detector technologies and develop new detector capabilities for future space-based missions, most often using photonic techniques. To that end, we present some ideas we are presently investigating: (i) tuning the wavelength response of detectors using applied electric or magnetic fields, (ii) detecting the full polarization vector of a signal within a single pixel of a quantum well detector, (iii) monolithic solid-state cooling of a detector using photoluminescence, and (iv) enhancement of weak electromagnetic fields using interactions with plasmons.

“…One can further decrease the error compared to the results of this paper by letting N R > 4 and designing the structure with a grating material that allows more light to penetrate to the deepest layers of the device. 14 The matrix M will be called the device's polarization response matrix, and in our model, M depends on more than 17 parameters including the structure of the pixel, the wavelength of the incident light, and the incidence angle of the incident light. The dependence on all these parameters is suppressed for simplicity.…”

At previous SPIE meetings, we reported on an optoelectronic device that measures the complete polarization state of incident infrared light in a single pixel and in a single frame for a narrow wavelength band ( δλ <0.05 µm). Using at least four quantum-well stacks and four linear gratings, each stacked alternating above the other, the device uses the interference among light paths to create a distinct pattern of photocurrents at each quantum-well stack coding for a specific polarization. In this paper, we will model the performance of this device, a quantum-well infrared single-pixel polarimeter (QWISPP), in the setting of a Fourier transform infrared (FTIR) imager. We model one column of QWISPP pixels detecting an interferogram. Using an FTIR with randomly varying QWISPP pixels to detect the interferogram, we discovered a technique that allows an 100× improvement in measured spectral-polarization uncertainty compared to the use of identical QWISPP pixels in an FTIR or grating spectrometer. The technique also enables a 15× improvement in the uniformity of the error across a sample spectrum. In other words, we turn into an advantage the imperfections in fabricating an FPA of QWISPPs.
