With the increasing demand for communication capacity, all-optical regeneration of multimode signals is a helpful technology network nodes and optical signal processors. However, difficulty regenerating in higher-order modes hinders practical application regenerators. In this study, we experimentally demonstrate 40 Gb/s NRZ-OOK TE0 TE1 via four-wave mixing (FWM) low-loss silicon-based nanowaveguide. By optimizing parameters waveguide section to enhance FWM conversion efficiency two modes,...
<title>Abstract</title> Quantum light sources with configurable photon lifetimes are essential for large-scale quantum circuits, enabling applications in programmable computing, various key distribution protocols, and tomography techniques. However, the fundamental trade-off between efficiency lifetime imposes significant challenges on design of high-performance large sources. Here, we report such chip-scale by harnessing unique feature parity-time (PT) symmetry. The core centers employing...
Scattering immune propagation of light in topological photonic systems may revolutionarize the design integrated circuits for information processing and communications. In optics, various have been developed, which were based on classical emulation either quantum spin Hall effect or valley effect. On other hand, combination both degrees freedom can lead to a new kind transport phenomenon, dubbed (QSVH), further expand number topologically protected edge channels would be useful multiplexing....
Optical parametric amplifiers (OPAs) are optical based on four-wave mixing processes, showing great potential for applications in communications, signal processing, quantum optics, etc. In recent years, significant progress has been made to integrated OPAs highly nonlinear micro-ring resonators (MRRs), benefiting from the greatly enhanced optical-matter interactions. Notable gain becomes available at unprecedented low power levels, allowing example source-integrated coherent frequency combs....
Photon pairs generated by employing spontaneous nonlinear effects in microresonators are critically essential for integrated optical quantum information technologies, such as computation and cryptography. Microresonators featuring high-quality (Q) factors can offer simple yet power-efficient means to generate photon pairs, thanks the intracavity field enhancement. In microresonators, it is known that photon-pair generation rate (PGR) roughly proportional cubic power of Q factor. However,...
Microcavities stand out as competitive tools in the development of quantum frequency combs (QFCs) for multiphoton entanglement sources, frequency-multiplexed single-photon and generation high-dimensional entangled states. However, presence waveguide dispersion hinders creation broadband QFCs, an issue that becomes increasingly critical quality factor microcavity increases. Here, we present a scheme to enhance spectral range QFCs by selectively manipulating pump resonance via parity-time...
Photon-pairs generation rate (PGR) based on spontaneous nonlinear processes in microresonators is found to be limited set by the quality (Q) factors of cavity resonances.
We propose a simple analytical formula for parametric gain and conversion efficiency of four-wave mixing effect in micro-ring resonator under the condition high injected pump power, which remains elusive. It is great importance integrated devices.
