Two-color photodetector

WebNov 1, 2016 · A novel mid-long-infrared two-color photodetector is proposed. It combines quantum cascade detector (QCD) and surface plasmonic coupling structure. The reflection spectrum and electric field are analyzed by algorithm of finite difference time domain method (FDTD). This QCD is sensitive to 4.4 μm and 9.0 μm infrared light. WebA dual-phase BeZnO alloy film with dual bandgap of ∼3.5 eV (∼355 nm) and ∼4.6 eV(∼270 nm) was artfully utilized as active layer to realize dual-color response. This photodetector shows a noticeable photovoltaic characteristic and can be utilized as an excellent self-powered device.
