Optical time-domain demultiplexing using semiconductor laser amplifiers

, 2022
S.218-221The huge bandwidth of optical fibres can be used for the transmission of high data rates multiplexed in the time-domain. The bottleneck will be the speed of the electronic signal processing at the termination of the transmission line.

OTDM to WDM format conversion based on cascaded SHG/DFG in a single PPLN waveguide [PDF]

, 2010
We propose and experimentally demonstrate error-free OTDM to WDM format conversion based on cSHG/DFG within a 30mm-long PPLN waveguide and a time-to-frequency domain conversion approach, which relies upon switching a linearly chirped ...

Between birch and berries: seasonal dietary niche partitioning among sympatric alpine herbivorous birds

Oikos, EarlyView.
Niche partitioning is important for the coexistence of closely related species, allowing species to reduce overlap in resource use despite shared ecological requirements. In alpine environments, harsh climatic conditions and low habitat complexity constrain opportunities for ecological segregation, making seasonal resource fluctuation especially ...

TDFPS-Designer: an efficient toolkit for barcode design and selection in nanopore sequencing

Genome Biology
Oxford Nanopore Technologies (ONT) offers ultrahigh-throughput multi-sample sequencing but only provides barcode kits that enable up to 96-sample multiplexing. We present TDFPS-Designer, a new toolkit for nanopore sequencing barcode design, which creates

Frequency-division multiplexer and demultiplexer for terahertz wireless links

Nature Communications, 2017
There is growing interest in the development of components to facilitate wireless communications in the terahertz but the characterization of these systems involve an unmodulated input. Here the authors demonstrate multiplexing and demultiplexing of data

Human Umbilical Cord Mesenchymal Stem Cell–Derived Exosomes Attenuate Renal Fibrosis by Suppressing Fibroblast Activation via the INHBA/PI3K/AKT Pathway

Pediatric Discovery, EarlyView.
MSC‐Exo derived from human umbilical cord (HucMSC‐Exo) downregulates INHBA expression, consequently modulating the PI3K/AKT signaling cascade. This regulation attenuates renal fibroblast activation and extracellular matrix deposition, thereby exerting a renoprotective effect against fibrosis.

Single-Gate 320-to-8x40 Gb/s Demultiplexing

The first experimental demonstration of 320Gb/s demultiplexing to eight simultaneous always-on 40Gb/s tributaries with near-zero latency is reported. Error-free demultiplexing is achieved by a single parametric processor operating in copy-and-sample mode

100 Gigabit Internet why and how : the technology behind it [PDF]

, 2010
The need to keep transmission capacity growing is a never ending process which is becoming more and more challenging to fulfill. Over the years we have witnessed data rates to grow from less than one bit per second all the way up to tens of Giga bits per
