Wavelength and polarization division multiplexing using the LP11 mode in a two-mode fiber for mode division multiplexing

open access: yes, 2011
The orthogonality of Mode Division Multiplexing (MDM) with Wavelength division multiplexing (WDM) and Polarization Division Multiplexing (PDM) is investigated applying WDM and PDM transmission over the LP11 mode in a few-moded fiber.

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

open access: yesAdvanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.

Integrated silicon multifunctional mode-division multiplexing system

open access: yesOptics Express, 2019
Chip-scale optical interconnects have been widely investigated using the wavelength-division multiplexing (WDM) technology, while it has been rarely reported using the mode-division multiplexing (MDM) technology that further improves communication capacity by using multiple spatial mode channels. On the other hand, to achieve large-bandwidth multi-core
