Analysis of parameter combinations for optimal soliton microcomb generation efficiency in a simple single-cavity scheme
arXiv:2209.03707 · doi:10.1103/PhysRevA.107.063508
Abstract
Dissipative Kerr solitons generated in high-Q optical microresonators provide unique opportunities for different up-to-date applications. Increasing the generation efficiency of of such signals is a problem of paramount importance. We provided comprehensive analysis and found optimal conditions providing maximal pump-to-comb conversion efficiency (up to 100\%) for the cases of a free-running and self-injection-locked pump lasers. The dependence of the optimal coupling rate on the pump power was revealed, in addition to the trade-off relations balancing the efficiency and the comb line number. The methods to increase the total comb power were also discussed.
arXiv commentFinal version does not include some of the basics of the theory (normalization section), but is more clear and full. The title is also changed. Old name "Detailed analysis of ultimate soliton microcomb generation efficiency"
