The miniaturization of metrology and precision spectroscopy systems requires robust, turn‐key microcombs with broad bandwidth, low threshold, and high efficiency. Here, high‐Q, dispersion‐engineered microresonators in a high‐confinement nonlinear SiC platform, combined with waveguide‐enabled thermal management and laser cooling, enable deterministic ...

Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes
This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping
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

Resonant States Reveal Strong Light–Matter Coupling in Nanophotonic Cavities
Photonic resonant states reveal characteristics of coupled light–matter systems that would otherwise be hidden by damping. Their trajectories (when tuning the optical resonance) undergo a qualitative change at the onset of strong coupling: They start swapping positions.

Lattice Resonances in Periodic Arrays of Time‐Modulated Scatterers
This work explores how periodic time modulation alters the collective optical behavior of periodic arrays of scatterers, shedding light on the critical role of collective effects in time‐varying photonic systems and unveiling new opportunities for amplification, active control, and nonreciprocal functionalities.
