Laser &Photonics Reviews, EarlyView.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 ...

FSR-Eliminated Vernier Racetrack Resonators Using Grating-Assisted Couplers
IEEE Photonics Journal, 2013 We present the design and experimental demonstration of a contra-directional grating-coupled racetrack resonator exhibiting the Vernier effect. The device consists of two racetrack resonators that are coupled together in a cascaded configuration.

Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, EarlyView.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Nanoholes Grating Couplers for Coupling Between Silicon-on-Insulator Waveguides and Optical Fibers
IEEE Photonics Journal, 2009 Simulation and experimental results of grating couplers composed of arrays of nanoholes are presented. The use of an array of holes instead of a conventional waveguide grating provides an additional degree of freedom in the design of the coupler, thus ...

Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes
Laser &Photonics Reviews, EarlyView.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

IEEE Photonics Journal, 2013 Si photonic devices are sensitive to the change in refractive index on the Si-on-insulator (SOI) platform. One of the critical limitations in the compact 3D photonic integration circuit is the through-Si-via (TSV)-induced stress, which affects the ...

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping
Laser &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
