[ALPS14-01(Invited)] Milliwatt-class terahertz signal sources using resonant tunneling diodes

*Safumi Suzuki¹ (1. Tokyo Institute of Technology)

Resonant tunneling diodes (RTDs) are one of the promising candidates for THz signal sources. Recently, a high output power of 11.8 mW at 450 GHz was achieved by a 36-element coherent array. Besides, attempts to increase in the output power of a single oscillator have been conducted. In this presentation, the recent studies for high-power RTD THz oscillators will be introduced.
