Three-dimensional mode-division multiplexing system

Optics Express, 2023
Blindly increasing the channels of the mode (de)multiplexer on the single-layer chip can cause the device structure to be too complex to optimize. The three-dimensional (3D) mode division multiplexing (MDM) technology is a potential solution to extend the data capacity of the photonic integrated circuit by assembling the simple devices in the 3D space.

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

Molecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

95.16-Gb/s Mode-Division-Multiplexing Signal Transmission in Free-Space Enabled by Effective-Conversion of Vector Beams

IEEE Photonics Journal, 2017
We introduce a high-efficient vector modes (VMs) conversion scheme by using Q-plate (QP) and half-waveplate based on higher-order Poincaré sphere model.

Nonlinear impairments in mode division multiplexed systems [PDF]

Optical Technologies in Telecommunications 2017, 2018
In this paper we consider nonlinear impairments of mode division multiplexed signals with QAM modulation in optical fibers with linear mode coupling of spatial modes. We simulate simultaneous propagation of fundamental mode and two first-order vortex modes in standard single mode fiber at 850 nm and propagation of fundamental mode and first- and second-

Unraveling LINE‐1 retrotransposition in head and neck squamous cell carcinoma

Molecular Oncology, EarlyView.
The novel RetroTest method allows the detection of L1 activation in clinical samples with low DNA input, providing global L1 activity and the identification of the L1 source element. We applied RetroTest to a real‐world cohort of HNSCC patients where we reported an early L1 activation, with more than 60% of T1 patients showing L1 activity.

Joint WDM and OAM Mode Group Multiplexed Transmission Over Conventional Multimode Fiber

IEEE Photonics Journal, 2023
To exploit the advantages of multimode fiber (MMF)-based transmission and to improve the overall capacity, transmission of OAM modes over a single wavelength needs to be replaced by multichannel transmission with the proper experimental demonstration in ...

Incoherent mode division multiplexing for high-security information encryption [PDF]

arXiv, 2023
In the age of information explosion, the conventional optical communication protocols are rapidly reaching the limits of their capacity, as almost all available degrees of freedom (e.g., wavelength, polarization) for division multiplexing have been explored to date.

Model for mode control in mode-division multiplexing system [PDF]

Advances in Computer Science Research, 2016
In the paper, a feasible mode control model based on Fourier Optical analysis is proposed to increase the transmission capacity of optical fiber communication. Our model combines fresnel diffraction and 4f system to implement mode control, where the phase-only spatial light modulator is employed as a spatial filter and the loss of amplitude of phase ...

Enhanced discovery of bacterial laccase‐like multicopper oxidase through computer simulation and metagenomic analysis of industrial wastewater

FEBS Open Bio, EarlyView.
We obtained potential bacterial laccase‐like multicopper oxidase (LMCO) sequences through metagenomic sequencing. All sequences exhibited significant differences from known LMCOs in databases. To select the most promising candidates, we performed structure prediction and molecular docking using alphafold2, metal3d and rosetta.

Amplifying Orbital Angular Momentum Modes in Ring-Core Erbium-Doped Fiber

Research, 2020
Lots of research efforts have been devoted to increase the transmission capacity in optical communications using orbital angular momentum (OAM) multiplexing. To enable long-haul OAM mode transmission, an in-line OAM fiber amplifier is desired.
