abstract = "Resonant cavity-enhanced photodetectors (RCE PDs) present a compelling alternative to broadband detection techniques in the field of gas detection and environmental sensing, due to the distinctive narrow-band absorption fingerprints of gases such as N2O (at 4.5 μm) or CO (4.6 μm). This characteristic aligns well with the operational mode of an RCE PD, whose VCSEL-like architecture results in a tuneable narrow-band spectral response with a significantly enhanced quantum efficiency. Additionally, unlike broadband detectors, RCE PDs are not subject to the broadband BLIP limit due to their high spectral selectivity, while the substantially reduced absorber volume offers commensurately reduced Auger and generation-recombination dark current densities. In this work, we present efforts to extend the operability of these structures beyond 4.0 μm wavelength by employing the type-II InAs/InAsSb superlattice as the absorber material. The tuneable bandgap of this structure allows to achieve and demonstrate a MWIR RCE PD with a highly thermally stable resonant response at ∼ 4.45 μm, a Q factor of 85-95, full-width-at-half-maximum of ∼ 50 nm and a peak quantum efficiency of 84% at 240 K - features which are promising for detection of gases such as CO and N2O. The broadband BLIP is also achieved at 180 K, a result which could potentially enable thermoelectrically cooled operation in the future. Finally, thanks to the inherent bandgap tunability of the InAs/InAsSb superlattice, extension of resonant response into the LWIR range is achievable with relatively straightforward changes to the already existing RCE PD structure. {\textcopyright} COPYRIGHT SPIE.
