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…
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…
Breaking the bandwidth-efficiency trade-off in soliton microcombs via mode coupling
Yang Liu, Andreas Jacobsen, Thibault Wildi +9
Dissipative Kerr solitons in optical microresonators have emerged as a powerful tool for compact and coherent frequency comb generation. Advances in nanofabrication have allowed pr…
Spectral dynamics in broadband frequency combs with overlapping harmonics
Weichen Fan, Furkan Ayhan, Thibault Wildi +8
Optical frequency combs and their spectra of evenly spaced discrete laser lines are essential to modern time and frequency metrology. Recent advances in integrated photonic wavegui…
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…
