Abstract
The efficiency η of sub-THz-to-DC energy conversion of a silicon-based plasmonic detector was studied. The dependence of the detector output signal on the incident radiation power was measured. It was shown that, in the linear-power region, the efficiency η increases with increasing power and saturates sublinearly. The maximum achieved values of η were 0.4% at a radiation frequency of 97 GHz. The measurements were carried out both at room temperature and when the detector was cooled to liquid nitrogen temperature.
