Mid-wavelength infrared (MWIR) detection is useful in a variety of scientific and military applications. Avalanche photodiodes can provide an advantage for detection as their internal gain mechanism can increase the system signal-to-noise ratio of a

In this work, we report guided-mode resonance enhanced room-temperature mid-wave infrared photodetectors with significant spectral-selective enhancement in responsivity and detectivity, all in the absorber thickness of only 250 nm.

We demonstrate all-epitaxial ultra-thin mid-wave infrared detectors integrated into guided-mode resonance structures. Peak external quantum efficiency above 50 % is reported at λ = 4.5 µm in a 250 nm thick absorber at 200 K.

We present the design and simulation of long-wave infrared detectors consisting of a doped-semiconductor ground plane underneath a thin Type-II superlattice (T2SL), patterned with a metallic antenna. We demonstrate enhanced absorption at the absorber
