摘要
Systems and methods for soliton microcomb-based precision dimensional metrology via spectrally-resolved interferometry are described. In an embodiment, the system includes a dual-pumped soliton microcomb generator comprising a pump, a microresonator, and an auxiliary pump and that generates a single-soliton microcomb, an erbium-doped fiber amplifier that amplifies a C-band section of the soliton microcomb and a non-polarizing beam splitter that divides the soliton microcomb pulses into a reference arm pulse and a measurement arm pulse for an interferometer and recombines the reference arm pulse and the measurement arm pulse into a recombined beam upon their return.
