151-as jitter, 22-GHz pulse train from a silica microcomb

Abstract

We characterized the timing jitter of 22-GHz pulse train from silica microcomb using self-heterodyne method. The timing jitter power spectral density at 100-kHz offset is 3.6×10-37 s2/Hz with integrated jitter of 151-as [100 kHz-3 MHz].
