The phase matching between the propagating fundamental and nonlinearly generated waves plays an important role in the efficiency of the nonlinear frequency conversion in macroscopic crystals. However, in nanoscale samples, such as nanoplasmonic struc

We demonstrate wideband flat bright-soliton Kerr-comb in thin-film foundry-compatible SiN platform. This is achieved using multi-segment coupled resonators. Multi-segment coupling with optimized coupling regions allow higher order dispersion engineer

Very high-Q photonic microdisk resonators in an air-clad thin-film SiN platform at near-visible wavelengths is demonstrated. The high Qs enabled by fabrication optimization result in the increased coherence time of the intracavity photon and provides
An integrated photonic platform is proposed for strong interactions between atomic beams and annealing-free high-quality-factor ( Q ) microresonators. We fabricated a thin-film, air-clad SiN microresonator with a loaded Q of 1.55 × 10 6 around the o

Inducing a large refractive-index change is the holy grail of reconfigurable photonic structures, a goal that has long been the driving force behind the discovery of new optical material platforms. Recently, the unprecedentedly large refractive-index
