1. A photonic-based microwave generator, comprising:
a mode-locked laser configured to generate an optical pulse train;
a feedback photodiode configured to generate, in response to detecting at least a portion of the optical pulse train, an error signal indicating relative intensity noise of the optical pulse train; and
a servo amplifier configured to process the error signal into a servo signal that controls intracavity power of the mode-locked laser to suppress the relative intensity noise of the optical pulse train;
wherein the mode-locked laser is configured such that timing jitter of the optical pulse train is reduced in response to the suppressed relative intensity noise.
