From hydrogels to eutectogels: Emerging platforms for stretchable electronics

open access: yesFlexMat, EarlyView.
The transition of wearable electronics toward long‐term reliability requires materials that resist dehydration without sacrificing tissue‐like softness and ionic conductivity. Eutectogels fulfill these demands by immobilizing deep eutectic solvents within tailored polymer networks.

4H-SiC microring opto-mechanical oscillator with a self-injection locked pump

open access: yesAPL Photonics
We have demonstrated, for the first time to our knowledge, self-injection locking of a distributed feedback diode laser to a multimode 4H-silicon carbide (4H-SiC) microring resonator, which is also used for the observation of resonant opto-mechanical ...

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator

open access: yesLaser &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.

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

open access: yesLaser &Photonics Reviews, EarlyView.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Doping‐Free Polymer Nanoparticle Engineering of n‐Type Organic Mixed Ion–Electron Conductors for Enhancement‐Mode Organic Electrochemical Transistors

open access: yesMacromolecular Rapid Communications, EarlyView.
We report a nanoparticle formulation strategy for the ladder polymer BBL that enables undoped enhancement‐mode OECTs. Controlled reprecipitation with DBSA yields stable nanoparticles, and spray‐coating forms dense, well‐connected films. The resulting devices exhibit strongly enhanced electrochemical response and transconductance, establishing a ...
