 Illustration of a silica wedge microresonator soliton-based low noise microwave generator. Phase modulation of the pump laser leads to injection locking that suppresses the long-term drift of the solitons (variations in the blue curve), while the short-term noise of the injected microwave signal (fluctuations in the green curve) is purified by the soliton dynamics. Thus, a low noise microwave can be synthesized (yellow curve).
