Dual-mode microresonators as straightforward access to octave-spanning dissipative Kerr solitons (vol 7, 066103, 2022)

Summary: The paper presents a design strategy for obtaining reliable dual modes in the silicon nitride platform with a separation of 10 GHz, which stabilizes soliton formation. The researchers demonstrate the generation of single-solitons spanning 1.5 octaves and the existence of ultra-wide soliton range up to 17 GHz. The proposed scheme also enables the generation of multi-solitons and soliton crystals with enhanced repetition rates and conversion efficiency.
