Abstract
We demonstrate a hybrid turnkey Kerr microcomb laser achieving single-soliton operation with 100 GHz free spectral range and 300 nm bandwidth, overcoming the integration and power limitations of previous microrod-based and wide-FSR hybrid systems. This performance, achieved in a single-soliton regime using an anomalous dispersion silicon nitride (Si3N4) microresonator integrated into a fibre Fabry-Perot cavity, marks a significant advancement in hybrid OFC generation. The resulting 64 comb lines, spanning the entire C-band above the -20 dBm level, deliver an average output power of 17 mW in single-mode fibre.
