Beam forming technologies are required for terahertz (THz) applications. A beam forming can be obtained using phase control by injection locking in an antenna array integrated with oscillators. A resonant-tunneling-diode oscillator is an antenna-integrated compact THz source, and arrayed device is easily realized. In this preliminary study, we report on the second harmonic generation and observation of injection locking in single RTD oscillator with injection of external signal.
