PWB-microresonator characterization in nonlinear regime. (a) Experimental setup used in the nonlinear characterization of the PWB-microresonator system. EOM electro-optical modulator, PC polarization controller, EDFA erbium-doped fiber amplifier, BPF tunable bandpass filter, FA fiber, V groove array, PWB photonic wire bond, FBG tunable fiber Bragg grating notch filter, PD photodetector, OSA optical spectrum analyzer, ESA electrical spectrum analyzer, Servo PID servo controller. (b) A single soliton optical spectrum generated in a MgF2 microresonator with a fitted \(sech^2(x)\) envelope shown by the dashed red line. (c) ESA trace at a 10 Hz resolution bandwidth (RBW) for an 80 kHz span of the 14.25 GHz beatnote signal, which corresponds to the comb line spacing in the soliton state.
