The on-chip generation of large and complex optical quantum states will enable low-cost accessible advances for technologies, such as secure communications computation.Integrated frequency combs are light sources with a broad spectrum evenly-spaced modes, commonly generated by four-wave mixing in optically-excited nonlinear micro-cavities, whose recent use state has provided solution scalable multi-mode sources.Pulsed particular interest, since they allow the singlefrequency-mode photons,...
The investigation of integrated frequency comb sources characterized by equidistant spectral modes was initially driven considerations toward classical applications, seeking a more practical and miniaturized way to generate stable broadband light. Recently, in the context scaling complexity optical quantum circuits, these on-chip approaches have provided new framework address challenges associated with non-classical state generation manipulation. For example, multi-photon high-dimensional...
Abstract Induced photon correlations are directly demonstrated by exploring two coupled nonlinear processes in an integrated device. Using orthogonally polarized modes within microring cavity, phase matching of different four‐wave mixing is achieved simultaneously, wherein both share one target frequency mode, while their other differ. The overlap these leads to the coupling processes, producing correlations. nature this process confirmed means time‐ and power‐dependent correlation...
Instantaneous frequency measurement (IFM) of microwave signals is a fundamental functionality for applications ranging from electronic warfare to biomedical technology. Photonic techniques, and nonlinear optical interactions in particular, have the potential broaden range beyond limits IFM systems.

The ability of laser systems to emit different adjustable temporal pulse profiles and patterns is desirable for a broad range applications. While passive mode-locking techniques have been widely employed the realization ultrafast pulses with mainly Gaussian or hyperbolic secant profiles, generation versatile shapes in controllable way from single system remains challenge. Here we show that nonlinear amplifying loop mirror (NALM) bandwidth-limiting filter (in nearly dispersion-free...

Energy efficiency is one of the most critical concerns for wireless sensor networks. By allowing nodes in close proximity to cooperate transmission form a virtual multiple-input multiple-output (MIMO) system, recent progress MIMO communications can be exploited boost system throughput, or equivalently reduce energy consumption same throughput and BER target. However, these cooperative strategies may incur additional cost overhead. In this paper, assuming that data collectors are equipped...
