Noise in Passively Mode-Locked Lasers [PDF]

, 1998
For the first time, phase fluctuations in the spectral intensity of the pulse train generated by passively mode-locked semiconductor lasers have been measured. The results reveal diffusion-like fluctuations of this phase.

UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

Advanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Multi-Spectral Quantum Cascade Lasers on Silicon With Integrated Multiplexers

Photonics, 2019
Multi-spectral midwave-infrared (mid-IR) lasers are demonstrated by directly bonding quantum cascade epitaxial gain layers to silicon-on-insulator (SOI) waveguides with arrayed waveguide grating (AWG) multiplexers.

Compact ultrabroad-bandwidth cascaded arrayed waveguide gratings

Optics Express, 2020
Here, we present a compact, high-resolution, and ultrabroad-bandwidth arrayed waveguide grating (AWG) realized in a silicon nitride (Si3N4) platform. The AWG has a cascaded configuration with a 1×3 flat-passband AWG as the primary filter and three 1×70 AWGs as secondary filters (i.e. 210 output channels in total).
