Abstract:
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.

Abstract:
Based on graphene heterostructure in chip-scale silicon nitride microresonators, optoelectronic control and modulation in frequency combs via group velocity dispersion modulation can be demonstrated. By tuning graphene Fermi level from 0.50 eV to 0.65 eV via electric-field gating, deterministic in-cavity group velocity dispersion control from anomalous (−62 fs/mm) to normal (+9 fs/mm) can be achieved with Q factor remaining high at 10. Consequently, both the primary comb lines and the full comb spectra can be controllable dynamically with the on/off switching of the Cherenkov radiation, the tuning of the primary comb lines from 2.3 THz to 7.2 THz, and the comb span control from zero comb lines to 781 phase-locked comb lines, directly via the DC voltage.
