Heterogeneous Integration of Multi‐Band Mode‐Locked and Single‐Mode Lasers on an Extended Commercial SiN Platform

Laser &Photonics Reviews, EarlyView.
Micro‐transfer printing enables GaAs and InP gain materials to be integrated on a commercial silicon nitride photonic platform. The resulting chip supports O‐ and C‐band comb and single‐mode lasers, demonstrating a scalable route toward multi‐material, multi‐wavelength, and multifunctional integrated light sources.

Dual‐Comb Spectroscopy With Fully Controlled Repetition Rate and Offset Frequency of Quantum Cascade Laser Frequency Combs

Laser &Photonics Reviews, EarlyView.
Independent control of the repetition rate and offset frequency is demonstrated in quantum cascade laser frequency combs using radio‐frequency injection and thermal tuning. A revised comb model anchored at optical frequencies captures the unique behavior under radio‐frequency injection and enables precise frequency control.

Real‐Time Observation of Soliton Buildup and Self‐Organization in a GHz Harmonic Mode Locked Fiber Laser

Laser &Photonics Reviews, EarlyView.
This image is an experimental recording of the buildup of harmonic mode‐locking in a fiber laser. The horizontal dimension corresponds to one cavity round trip, where the laser field intensity is displayed in a color scale. The vertical dimension is the evolution time in logarithmic scale, spanning from microseconds to seconds.

The Algorithmic Well‐Being Paradox: When AI Decision Delegation Helps and Hurts Consumer Well‐Being

Psychology &Marketing, EarlyView.
ABSTRACT As generative AI increasingly shapes consumer decision‐making, its implications for consumer well‐being remain unclear. Existing research largely focuses on the trade‐off between algorithmic efficiency and autonomy loss. This research advances understanding by proposing the algorithmic well‐being paradox, whereby the same AI delegation can ...

Mass Spectrometry in Authentication and Forensic Approaches for Determining the Origin of Hazardous Chemicals

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...
