Paper Abstract

Solid state frequency multipliers extend the operating frequency range of Backward Wave Oscillators (BWOs) to 2.6 THz, enabling continuously tunable, narrow linewidth THz sources across the 0.1-2.6 THz range. Power conversion efficiency of frequency multipliers can be improved substantially by optimizing impedance matching between millimeter wave BWOs and frequency multipliers. Performance of sub-millimeter wave BWOs combined with frequency multipliers is limited by multi-mode output of these BWOs and lower power conversion efficiency of solid state multipliers operating above 1 THz.
