Asynchronous Terahertz-field sampling with soliton microcombs
Alexandra Sakharova, Alexander E. Ulanov, Konstantin Wenzel +6
Terahertz time-domain spectroscopy records the electric field of terahertz transients and underpins applications from materials science to non-destructive testing. Asynchronous opt…
Bright solitons in hybrid-dispersion photonic crystal microresonators
Alexander E. Ulanov, Lukas Bengel, Bastian Ruhnke +2
Bright dissipative Kerr solitons in optical microresonators provide chip-scale sources of ultrashort pulses and frequency combs. Their properties are defined by the cavity dispersi…
Photonic-crystal microresonator-based LiDAR engine
Kenji Nishimoto, Alexander E. Ulanov, Thibault Wildi +1
Self-injection-locked (SIL) narrow-linewidth lasers based on high-Q microresonators are promising sources for frequency-modulated continuous-wave (FMCW) LiDAR, but the SIL mechanis…
Attosecond-level synchronisation of chip-integrated oscillators
Alexander E. Ulanov, Bastian Ruhnke, Theia El Sharkawy +4
Synchronised laser oscillators are essential for probing the fastest processes in chemistry, materials science, and biology down to atto-second timescales. Tight synchronisation is…
Quadrature squeezing in a nanophotonic microresonator
Alexander E. Ulanov, Bastian Ruhnke, Thibault Wildi +1
Squeezed states of light are essential for emerging quantum technology in metrology and information processing. Chip-integrated photonics offers a route to scalable and efficient s…
Laser diode self-injection locking to an integrated high-Q Fabry-Perot microresonator
Alexander E. Ulanov, Thibault Wildi, Utkarsh Bhatnagar +1
Self-injection locking (SIL) of laser diodes to microresonators is a powerful technique that enables compact narrow linewidth lasers. Here, we extend this technique to chip-integra…
Phase-stabilised self-injection-locked microcomb
Thibault Wildi, Alexander E. Ulanov, Thibault Voumard +2
Microresonator frequency combs (microcombs) hold great potential for precision metrology within a compact form factor, impacting a wide range of applications such as point-of-care…
Sideband Injection Locking in Microresonator Frequency Combs
Thibault Wildi, Alexander Ulanov, Nicolas Englebert +2
Frequency combs from continuous-wave-driven Kerr-nonlinear microresonators have evolved into a key photonic technology with applications from optical communication to precision spe…
