Overcoming the Manley-Rowe limit for CW terahertz generation in Q-engineered multimodal cavity Salamin, Yannick Roques-Carmes, Charles Lin, Zin Johnson, Steven G. Soljačić, Marin We present a method to overcome the Manley-Rowe limit in a <jats:italic>Q</jats:italic>-factor engineered multimodal nonlinear cavity. Cascading nonlinear processes enable continuous-wave terahertz generation with a theoretical conversion efficiency of 98.8%.
