NPR-NLMMI hybrid mode-locked fiber laser with an SMF-PCF-GIMF-SMF saturable absorber [PDF]

Nanotechnology and Precision Engineering
This study demonstrates a hybrid mode-locked fiber laser by incorporating a single-mode fiber-photonic crystal fiber-graded-index multimode fiber-single-mode fiber (SMF-PCF-GIMF-SMF) structure as a saturable absorber (SA) into a nonlinear polarization ...

Mode-locking via dissipative Faraday instability

Nature Communications, 2016
Dissipative Faraday instability by periodic zig-zag modulation of spectral losses can lead to pattern formation in variety of systems. Here, the authors employ this nonlinear instability as a technique to achieve high-order harmonic mode-locking in a ...

In Situ Interfacial Assembly of Dynamic Semi‐Interpenetrating Biopolymer Networks for Robust and Mechanically Adaptive Droplet Interfaces

Advanced Functional Materials, EarlyView.
A dynamic interfacial semi‐interpenetrating polymer network is constructed by sequential assembly of β‐sheet‐rich SF and CS‐RL. The SF framework provides mechanical strength, while dynamically associated CS‐RL enables local rearrangement, allowing droplets to rapidly reconfigure without loss of interfacial integrity.

Rational Harmonic Mode-Locking of a Fiber Optical Parametric Oscillator at 30 GHz

IEEE Photonics Journal, 2011
We demonstrate rational harmonic mode-locking of a fiber optical parametric oscillator (FOPO) in which the parametric gain serves as an all-optical mode-locker.

Observation of Soliton Molecules in a Robust All PM Mode-Locked Fiber Laser With Nonreciprocal Phase Bias

IEEE Photonics Journal, 2021
We report the first experimental observation, to the best of our knowledge, of soliton molecules in a robust all polarization-maintaining (PM) mode-locked fiber laser with a nonreciprocal phase bias that results in a low self-starting threshold and ...

How carrier memory enters the Haus master equation of mode-locking

, 2020
We present a generalization of the Haus master equation in which a dynamical boundary condition allows to describe complex pulse trains such as the Q-switched and harmonic transitions of passive mode-locking as well as the weak interactions between ...

Advances in 3D Bioprinting for Breast Cancer Modeling: Tumor Microenvironment, Metastasis, and Drug Screening

Advanced Healthcare Materials, EarlyView.
Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...
