Compact and coherent solid-state sources are important key components for various applications of the THz waves.For semiconductor single oscillators, quantum cascade lasers are being intensively studied from the optical device side.In the electron device side,resonant tunneling diodes (RTDs) have been considered as one of the candidates for THz oscillators at room temperature [1]-[4].In this paper, we report on our recent results of the RTD oscillators for compact THz sources.
