New effect in Josephson mixing of a submillimeter laser signal and a microwave signal

An oscillatory quasiperiodic structure is observed in the I-V characteristic of a Josephson point contact irradiated by a 525.5-GHz submillimeter laser signal and a 4.5-GHz microwave signal. Solving the resistively shunted Josephson (RSJ) model by a novel approach, in which the supercurrent is treat...

Description
Summary:An oscillatory quasiperiodic structure is observed in the I-V characteristic of a Josephson point contact irradiated by a 525.5-GHz submillimeter laser signal and a 4.5-GHz microwave signal. Solving the resistively shunted Josephson (RSJ) model by a novel approach, in which the supercurrent is treated as a perturbation, the structure is shown to result from higher-order mixing processes.
