Utilizing Efficient Light - Heat Conversion in Aluminum Perfect Absorbers for Spectrally Selective Infrared Detectors

Not Accessible

Plasmonic perfect absorbers (PAs), which can exhibit near-unity absorptivity at desired wavelengths, have been widely studied over the past decade with respect to their remarkable optical properties and wide applications. In particular, the PAs operating in the middle-wavelength infrared (MWIR) region have been extensively proposed in photonics and optoelectronics such as wavelength-selective thermal emitters [1,2], molecular sensor [3] and selective infrared detector [4]. In this report, by taking advantage of the spectrally-selective and efficient light-heat conversion in the aluminum perfect absorber (AlPA) as a spectrally selective absorbing electrode, combined with a highly c-axis oriented ZnO film crystal, we demonstrate a compact design for wavelength-selective pyroelectric infrared detectors [5].
