Electro-optic (EO) modulation is a key functionality to have on-chip. However, achieving a notable linear EO effect in stoichiometric silicon nitride has been a persistent challenge due to the material's intrinsic properties. Recent advancements revealed t ...
We develop a device consisting of two silicon nitride microresonators coupled by photo-induced second-order nonlinearity. By electrically reconfiguring its linear properties, we engineer efficient resonant frequency doubling in the telecom band and show th ...

We demonstrate Si3N4 photonic integrated circuits featuring ultra-low propagation loss and tight optical confinement, fabricated with a subtractive process. We report an increase in propagation loss in Si3N4 waveguides after exposure to ultraviolet (UV) ir ...
We propose a system of coupled microring resonators for the generation frequency combs and dissipative Kerr solitons in silicon at telecommunication frequencies. By taking advantage of structural slow-light, the effective non-linearity of the material is e ...
Optical frequency combs have a wide range of applications in science and technology(1). An important development for miniature and integrated comb systems is the formation of dissipative Kerr solitons in coherently pumped high-quality-factor optical micror ...
