Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator

Laser &Photonics Reviews, EarlyView.
This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.

Optical‐to‐Microcomb Stability Transfer for Ultrastable Timing and Microwave/Millimeter‐Wave Generation

Laser &Photonics Reviews, EarlyView.
This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.

Digital fire technologies and community networks: Cultivating just sociotechnical practices for living with planetary change

People and Nature, EarlyView.
Abstract Fires are expanding in frequency and intensity worldwide due to climate change and land‐use transformations. At the same time, fire often plays a regenerative role in ecosystems. Traditional and cultural practices incorporate fire use for landscape management and landscape renewal. In this complex matrix of fire ecologies, digital technologies
