Mode‐Locked Pulse Generation in Plasmonic Lattices

Laser &Photonics Reviews, EarlyView.
The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform

Laser &Photonics Reviews, EarlyView.
Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.

NIR/VIS Dual‐Comb Spectroscopy Comparing High and Low Repetition Rate Regimes

Laser &Photonics Reviews, EarlyView.
This work compares dual‐comb spectroscopy at lower and higher repetition rates, emphasizing the inherent trade‐off between spectral and temporal resolution. The 80 MHz system provides high‐resolution spectra suitable for analyzing complex molecular structures, whereas the free‐running 1 GHz platform enables fast measurements for real‐time trace gas ...

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

Laser &Photonics Reviews, EarlyView.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...
