Enhancement and Speed‐Up of Carrier Dynamics in A Dielectric Nanocavity with Deep Sub‐Wavelength Confinement

Laser &Photonics Reviews, EarlyView.
This work presents the first experimental investigation of ultrafast dynamics in dielectric bowtie nanocavities, featuring deep‐subwavelength mode confinement. Measurements reveal enhanced two‐photon absorption, sub‐picosecond carrier relaxation, and strong pump–probe interactions, demonstrating clear advantages over conventional nanocavities for low ...

Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

Laser &Photonics Reviews, EarlyView.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Amplification of Light‐Ultrasound Interaction in a Pi‐Shifted Fiber Bragg Grating for Enhanced Ultrasonic Sensitivity

Laser &Photonics Reviews, EarlyView.
By precisely engineering the geometry of a fiber‐based optical resonator, the interaction between confined light and external ultrasound waves is significantly amplified without sacrificing light confinement, boosting the ultrasound detection sensitivity beyond 0.5 mPa/√Hz.
