Paper Abstract

The operating frequency range of millimeter wave Backward Wave Oscillators (BWOs) are extended to 2.2 THz using solid state frequency multipliers, enabling continuously tunable, narrow linewidth THz sources across the 0.1-2.2 THz range. Power conversion efficiency of frequency multipliers was improved substantially by optimizing impedance matching between the BWOs, multipliers, and free space. Impedance matching extracts more THz power out of BWOs coupled to frequency multipliers, than is emitted from BWOs radiating into free space.
