Fig. 3: Strong drive response and photonic energy diagrams.
From: High-impedance microwave resonators with two-photon nonlinear effects
a The two-tone measurement of Fig. 2d measured for two orders of magnitude stronger drive powers P1. b The second tone transmission coefficient T measured as a function of the two drive frequencies f1 and f2 at fixed P1 = 450 aW and P2 = 27 aW. c The energy diagram measurement of Fig. 3b repeated for a stronger drive power of P1 = 14, 000 aW.
