An IR sensor device may include an IR image sensor having an array of IR sensing pixels, and a readout circuit coupled to the IR image sensor and configured to sense sequential images. The IR sensor device may include a controller coupled to the readout circuit and configured to cause the readout circuit to apply a voltage to the IR image sensor between sensing of the sequential images.

Radiation-defect mitigation in InAs/GaSb strained-layer superlattice infrared detectors and related methods

A quantum cascade laser (QCL) may include a QCL crystal having an emitting facet, and an active region adjacent the emitting facet, the emitting facet for providing an electromagnetic beam. The QCL may include an optical cavity comprising a mirror being external to the QCL crystal, and for redirecting the electromagnetic beam into the active region of the QCL crystal to provide optical feedback, and a driver circuit for driving the QCL crystal with a constant current. The QCL may include a controller coupled to the optical cavity and for dynamically and autonomously aligning the optical cavity based upon an error signal from the QCL crystal to maintain stable the optical feedback into the active region of the QCL crystal.
