This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

Toward Highest Frequency, Phase‐Sensitive Electric Field Sensing Enabled by Plasmonic Circuits
An electromagnetic field sensor using an optical sensor head for distortion‐free, high‐sensitivity measurements with potential for high‐frequency operation is presented. The frequency response is enabled by an antenna‐integrated plasmonic modulator. The sensitivity is calculated, and optimizations to obtain thermal‐background‐limited sensitivity are ...

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

An optical approach is proposed for real‐time and high‐precision detection of the magnetostrictive deformation of an yttrium‐iron‐garnet sphere in three dimensions, based on the deformation induced spatial high‐order modes of the scattered field, postselection, and balanced homodyne detection.
