Integrated Photonic Modulator Circuit With Programmable Intensity and Phase Modulation Response
A platform‐agnostic programmable modulation circuit is introduced to enable tunable and universal optimization of integrated photonic modulators. By flexibly controlling carrier amplitude and phase, the approach adapts to diverse device characteristics without structural redesign.

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.

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Theory of Supercritical Coupling and Generalized Bound States in the Continuum
We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...
