Broadband Mode Converter With Customizable Modal Ratio Leveraging Subwavelength Engineering for Advanced Multimode Silicon Photonics

Laser &Photonics Reviews, EarlyView.
This work introduces a customizable mode converter for multimode silicon photonics, enabling precise control over the conversion ratio between optical modes. The device operates across a broad wavelength range (1350–1700 nm) with 15 distinct conversion levels.

Deterministic Fiber‐Optic Spectral Engineering Enables Three‐Color Multiplexed Two‐Photon Microscopy

Laser &Photonics Reviews, EarlyView.
A simulation‐guided spectral‐engineering framework maps the nonlinear parameter space of a fiber laser platform to identify balanced three‐band excitation states. The resulting 960, 1080, and 1175 nm femtosecond pulses deliver nJ‐level energies for low‐cross‐talk chromatically multiplexed two‐photon microscopy.

Frontiers of Bright CEP‐Stable Broadband Infrared Sources

Laser &Photonics Reviews, EarlyView.
Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.
