Abstract

Kerr frequency comb generated in ultra-high Q whispering gallery mode (WGM) microresonators is a promising light source for ultra-compact photonic devices due to its potential advantages of low power consumption and possibility of chip integration. We introduce a technique to stabilize and control effective generation of dissipative Kerr solitons (DKS) in nonlinear crystalline microresonators using regular commercial broad spectrum multi-frequency CW laser diodes (1550 nm; P ∼ 200 mW), self-injection locked to magnesium fluoride microresonators (Q > 109).
