The Josephson plasma emitter is a terahertz light source with a characteristic that the bias voltage and radiation frequency are proportional. By modulating the bias voltage, our group succeeded in frequency modulating the radiated terahertz waves. In our talk, we will show experimental results obtained by finely changing the frequency of the applied modulating voltage and discuss the time evolution of the Josephson junction synchronization phenomenon.
