Experimental investigation of a passively mode-locked fiber laser based on a symmetrical NOLM with a highly twisted low-birefringence fiber [PDF]

, 2008
We experimentally investigate the passive mode-locking operation of a figure eight-fiber laser based on a symmetrical nonlinear optical loop mirror (NOLM) with a highly twisted low-birefringence fiber in the loop.

Functional Disorder at the Neural Interface: How Disordered Nanostructures Promote Proper Growth and Differentiation in In Vitro Neural Cultures

Advanced Science, EarlyView.
This work provides a practical guide for neuroengineers to design advanced neural interfaces, embracing and tailoring the concept of functional disorder. By bridging 2D and 3D in vitro models, this work highlights how non‐periodic, spatially heterogeneous, multiscale nanotopography can enable more physiologically relevant platforms for studying neural ...

Mode-locked Nd-doped microstructured fiber laser

Optics Express, 2004
We demonstrate passive mode-locking of a microstructured fiber laser for the first time. The Nd-doped microstructured fiber exhibits a reduced dispersion at 1060 nm. A semiconductor saturable absorber mirror is used for passive mode-locking. Stable pulse formation with a pulse duration of about 26 ps and a pulse energy of 0.7 nJ is observed.
