Strong Coupling‐Induced Topological Edge‐State Laser in 1D High‐Contrast Grating
Advanced Photonics Research, EarlyView.This study manipulates lattice constants and filling factors in 1D high‐contrast gratings to induce strong and weak coupling, enabling topological and trivial states. Demonstrating topological edge‐state lasers with improved robustness, lower thresholds, and narrower linewidths, the design supports novel topological laser cavity advancements ...

Advanced Photonics Research, EarlyView.A compact self‐detecting dual‐comb spectroscopy (DCS) system based on dispersion‐engineered, high‐speed packaged quantum cascade lasers (QCLs) at λ≈4.6 μm under coherent injection locking is demonstrated. Broad multiheterodyne comb signal with reduced tooth linewidths by orders of magnitude is recorded.

Advanced Sensor Research, EarlyView.This work overcomes long‐standing crucial technical difficulties in miniaturizing micro‐wave detectors, caused by the longer‐wavelength diffraction limit, with carbon nanotube (CNT) film photo‐thermoelectric sensors. The CNT film sensor exhibits sensitive micro‐wave detection operations with signal‐to‐noise ratios over 1400 at compact device sizes ...
