Semi-classical analysis of noise squeezing in Kerr microresonators
Sara Persia, Lev Fandeev, Fuchuan Lei +5
Kerr microresonators are integrated nonlinear devices widely used to generate classical optical frequency combs and nonclassical states of light. In particular, they provide a prom…
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…
-2 self-referencing for silicon nitride photonics via a heterogeneously integrated lithium niobate layer
Weichen Fan, Bastian Ruhnke, Camiel Op de Beeck +4
Heterogeneous integration combines complementary material properties in a single photonic platform. Here, we demonstrate on-chip -2 self-referencing in a heterogeneously inte…
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…
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…
Supercontinua from integrated gallium nitride waveguides
Weichen Fan, Markus Ludwig, Ian Rousseau +4
Supercontinua are broadband spectra that are essential to optical spectroscopy, sensing, imaging, and metrology. They are generated from ultrashort laser pulses through nonlinear f…
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…
