Lithium niobate is a critical material extensively used in nonlinear optics. The recent development of nanophotonic lithium niobate devices further extends their importance with enhanced nonlinearity and scalability. However, the performance of nonlinear optical processes in lithium niobate is influenced by the …

Nonlinear frequency mixing is of critical importance in extending the wavelength range of optical sources. It is also indispensable for emerging applications such as quantum information and photonic signal processing. Conventional lithium niobate with periodic poling is the most widely used device …

Photons play a critical role in future quantum technology, due to its indispensable function as quantum information carrier over long distances. The efficient generation of quantum states is the foundation of quantum photonic technology. In particular, advanced quantum states beyond single-photon pairs …

Current integrated optical isolators have limited bandwidths due to stringent phase-matching, resonant structures, or absorption. We demonstrate broadband optical isolation in thin-film lithium niobate that simultaneously achieves ∼ 100 nm isolation bandwidth at visible and telecom wavelengths.

Optical isolators are an essential component of photonic systems. Current integrated optical isolators have limited bandwidths due to stringent phase-matching conditions, resonant structures, or material absorption. Here, we demonstrate an ultra-broadband integrated optical isolator in thin-film lithium niobate photonics. We use dynamic …

Several extremely influential theories, including the multiple streams approach and punctuated equilibrium theory, predict that dramatic policy change occurs when problems are reframed. However, there is little direct evidence of how framing messages influence policymaker attitudes, perceptions, and behaviors. In an online …

Identities compactly describe properties of a mathematical expression and can be leveraged into faster and more accurate function implementations. However, identities must currently be discovered manually, which requires a lot of expertise. We propose a two-phase synthesis and deduplication pipeline that discovers …

This article explores the drivers of the development of strategic commissioning over the last two decades, its limitations, and the implications of its rapid spread. It suggests that the differences between government departments have allowed scope for local variations, which have been …
