3 W average-power high-order mode pulse in dissipative soliton resonance mode-locked fiber laser

Nanophotonics, 2021
Recently high-order modes (HOMs) lasers have been extensively investigated due to their potential applications in mode-division multiplexing. In this paper, we present two schemes of generating HOMs from the mode-locked fiber lasers (MLFLs) in the ...

Fixed-rate-breaking All-optical OFDM system using time-domain hybrid PAM with sparse subcarrier multiplexing and power-loading for optical short-reach transmission

, 2020
All-optical TDHP-OFDM system with four-sparse-subcarrier-multiplexing and power-loading has been proposed for data-rate-adaptive transmission. 40-Gbit/s, 60-Gbit/s, and 80-Gbit/s can be selected by changing the ratio of PAM2 and PAM4, and all BERs ...

Broadband Backhaul Communication for Stratospheric Platforms: The Stratospheric Optical Payload Experiment (STROPEX) [PDF]

, 2006
A high bitrate optical downlink was performed by the stratospheric optical payload experiment (STROPEX), a part of the EU CAPANINA project. The STROPEX objectives were to design and build the necessary hardware to demonstrate an optical backhaul downlink

Lysyl oxidase (LOX)‐mediated remodeling of the extracellular matrix

FEBS Letters, EarlyView.
The lysyl oxidase (LOX) family of enzymes drives extracellular matrix remodeling by oxidizing collagen, elastin, and fibronectin, promoting covalent cross‐link formation. This activity regulates tissue architecture and mechanical properties, while its dysregulation contributes to fibrosis, cardiovascular disease, glaucoma, connective tissue disorders ...
