Extended Data Fig. 1: Chip-scale broadband OPA demonstrations.
From: Low-power integrated optical amplification through second-harmonic resonance
(a) Gain versus pump power for chip-scale OPAs in the literature (see Extended Data Table 1). Green circles represent phase-insensitive amplification measurements and red squares phase-sensitive amplification. Darker points correspond to data from this work (see Fig. 3). Curves are simulations using the same parameters as Section III. (b) Gain rate (at max reported power) vs loss rate of chip-scale OPAs. Dashed lines are lines of constant nonlinearity-to-loss ratio. Those references that did not include loss rate information could not be plotted.
