中文摘要 | We report the optical response characteristics of Al/Ti bilayer transition edge sensors(TESs), which are mainly comprised of Al/Ti bilayer thermometers and suspended SiN membranes for thermal isolation. The measurement was performed in a3 He sorption refrigerator and the device's response to optical pulses was investigated using a pulsed laser source. Based on these measurements, we obtained the effective recovery time(τeff) of the devices at different biases and discussed the dependence of τeffon the bias. The device with a 940 μm× 940 μm continuous suspended SiN membrane demonstrated a fast response speed with τeff= 3.9 μs, which indicates a high temperature sensitivity(α = T/R· dR/dT =326). The results also showed that the TES exhibits good linearity under optical pulses of variable widths.; We report the optical response characteristics of Al/Ti bilayer transition edge sensors(TESs), which are mainly comprised of Al/Ti bilayer thermometers and suspended SiN membranes for thermal isolation.
