Figure 5

Measured (a1) efficiency of probe transmission signal and (b1) efficiency of enhanced four wave mixing band gap signal (Er) versus Δ2 from 160 MHz to 400 MHz with Δ3 = 230 MHz and Δ1 = 280 MHz, when we set the power of E2 (P2) as (Black) 21.5 mW, (Red) 17.0 mW, (Blue) 13.6 mW, (Pink) 9.7 mW, (Green) and 6.2 mW, respectively. (a2) and (b2) are the theoretical calculations of (a1) and (b1), respectively. (c) Gain factor of the amplifier versus P2. (Solid circles are the experimental data points, while the solid line is theoretical fitting result).
