Monolithic piezoelectric control of soliton microcombs
Junqiu Liu, Hao Tian, Erwan Lucas +9
High-speed laser frequency actuation is critical in all applications employing lasers and frequency combs, and is prerequisite for phase locking, frequency stabilization and stabil…
Observation of stimulated Brillouin scattering in silicon nitride integrated waveguides
Flavien Gyger, Junqiu Liu, Fan Yang +6
Silicon nitride (Si3N4) has emerged as a promising material for integrated nonlinear photonics and has been used for broadband soliton microcombs and low-pulse-energy supercontinuu…
Packaged photonic chip-based soliton microcomb using an ultralow-noise laser
Arslan S. Raja, Junqiu Liu, Nicolas Volet +7
Photonic chip-based soliton microcombs have shown rapid progress and have already been used in many system-level applications, including coherent communications, astrophysical spec…
Thermo-refractive noise in silicon nitride microresonators
Guanhao Huang, Erwan Lucas, Junqiu Liu +5
Thermodynamic noise places a fundamental limit on the frequency stability of dielectric optical resonators. Here, we present the characterization of thermo-refractive noise in phot…
Nanophotonic soliton-based microwave synthesizers
Junqiu Liu, Erwan Lucas, Arslan S. Raja +7
Microwave photonic technologies, which upshift the carrier into the optical domain to facilitate the generation and processing of ultrawide-band electronic signals at vastly reduce…
Electrically pumped photonic integrated soliton microcomb
Arslan S. Raja, Andrey S. Voloshin, Hairun Guo +11
Optical frequency combs have revolutionized frequency metrology and timekeeping, and can be used in a wide range of optical technologies. Advances are under way that allow dramatic…
