Optical injection locking can be used to isolate and amplify individual comb modes from an optical frequency comb (OFC). However, it has been observed that for narrow spaced OFCs (e.g.

Four-photon entanglement generation with integrated optical frequency combs
We demonstrate the generation of four-photon entangled quantum states with integrated optical frequency comb sources. We measure four-photon quantum interference with a visibility above 89%, and perform quantum state tomography revealing a fidelity ...

Loss, persistence and reversal of phenotypic traits
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Optical frequency combs and optical frequency measurements
Self-referenced optical frequency combs are nowadays the instrument of choice in time and frequency metrology when dealing with high accuracy and stability measurements of optical frequencies. Beyond this purely measurement activity, they also have new high performance applications, such as low phase noise microwave generation and transfer of spectral ...

Two-Way Optical Time and Frequency Transfer Over a 20-km Fiber Link Based on Optical Frequency Combs
Traditional high-precision long-distance time–frequency transmission requires a complex compensation structure and a continuous optical link, which make high-precision transmission difficult.

This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

Downsampling of optical frequency combs
We demonstrate repetition-rate downsampling of optical frequency combs by way of pulse gating. The reduced repetition rate enables increased pulse energy, facilitating efficient spectral broadening and f-2f interferometry. To explore the technique, we downsample a 250 MHz repetition-rate comb to 25 MHz and detect the carrier-envelope offset frequency ...

ABSTRACT Objective Anorexia nervosa (AN) is a serious illness in which more than half of all deaths are due to malnutrition. Critically low energy and protein intake are known causes of massive weight loss, whereas micronutrient deficiencies due to a low‐calorie food pattern remain poorly characterized in children with AN. Micronutrient deficiencies in
