Photonic integrated circuits with second-order (χ (2)) nonlinearities are rapidly scaling to
remarkably low powers. At this time, state-of-the-art devices achieve saturated nonlinear …

This article reviews recent progress in quasi-phasematched $\chi^{(2)} $ nonlinear
nanophotonics, with a particular focus on dispersion-engineered nonlinear interactions …

Multimode silicon resonators with ultralow propagation losses for ultrahigh quality (Q) factors
have been attracting attention recently. However, conventional multimode silicon resonators …

Silicon Photonics, the technology where optical devices are fabricated by the mainstream
microelectronic processing technology, was proposed almost 30 years ago. I joined this …

We propose a deterministic, measurement-free implementation of a cubic phase gate for
continuous-variable quantum information processing. In our scheme, the applications of …

Silicon nitride (Si3N4) is an ever-maturing integrated platform for nonlinear optics but mostly
considered for third-order [χ (3)] nonlinear interactions. Recently, second-order [χ (2)] …

Random numbers are a basic ingredient of simulation algorithms and cryptography, and
play a significant part in computer simulation and information processing. One prominent …

Numerical modeling of ultrashort pulse propagation is important for designing and
understanding the underlying dynamical processes in devices that take advantage of highly …

We present the design, preparation, and performance optimization of strip waveguide in
chalcogenide glass (ChG) for broadband supercontinuum (SC) generation. Ternary Ge-Sb …

Compact chip-scale comb sources are of significant interest for many practical applications.
