Inverse Spectral Design of Kerr Microcomb Pulses

摘要

Xon-linear wave mixing in optical microresonators offers new perspectives for the realization of compact optical frequency :microcombs', holding many promising applications. These typically rely on dissipative soliton formation in driven nonlinear passive cavities with anomalous dispersion, yielding a sech pulse shape. Here, we use a genetic algorithm to 'invert' the Lugiato-Lefever equation that models these systems, in order to find the optimum arbitrary dispersion profile needed to achieve a microcomb with a targeted spectral shape. We consider several use cases, such as generating near gaussian pulses, or a telecom-optimized microcomb. as well as optimize a dispersive wave position and power.
