A 16-channel spatial-division multiplexed transceiver is demonstrated using a multicore fiber coupled to dense array of co-integrated 56Gb/s GeSi electro-absorption modulators and photodetectors, realizing 896Gb/s aggregate bi-directional bandwidth in 1.47mm2 silicon footprint.
Abstract Objective . Brain–machine interfaces are key components for the development of hands-free, brain-controlled devices. Electroencephalogram (EEG) electrodes particularly attractive harvesting neural signals in a non-invasive fashion. Approach. Here, we explore use epitaxial graphene (EG) grown on silicon carbide detecting EEG with high sensitivity. Main results and significance. This dry approach exhibits markedly improved skin contact impedance when benchmarked to commercial...
A multichannel tapered coupler interfacing standard 250-µm-pitch low-NA polarization-maintaining fiber arrays with ultra-dense 20-µm-pitch high-NA silicon waveguides is designed, fabricated, and tested, demonstrating coupling losses below 1 dB injection bandwidths of 160 Gb/s/channel.
SDM using uncoupled or coupled core multicore fibers promises to increase the bandwidth density in optical links. In addition, these form a platform for various sensing systems, including 3D shape sensing. Both applications will be advanced by low return loss fanout-multicore fiber assembly demonstrated here.
MCFs have been developed for submarine deployment. Reliability and insertion loss are gating factors this demanding application. Here we demonstrate a 0.15-dB-loss fanout, which is fusion spliced to pure-silica two-core submarine-grade MCF.
We demonstrate a hexagonal, monolithic optical fiber array matched to 37 vertical grating couplers with 40 μm pitch for silicon photonics interface, standard deviation of coupling across all channels 0.7 dB.
Microformed, adiabatically tapered optical waveguides utilizing a "vanishing core" concept possess unique properties that make them useful for dense multichannel coupling, spatial division multiplexing communications and sensing, polarization control, amplification.

Real-world SDM deployment requires the development of a supporting ecosystem. Recent technological advancements allow for volume production key components this ecosystem, MCF fanouts, which meet demanding performance requirements.
A novel means of implementing periodicity into a glass fiber, which allows for polarization as well wavelength selectivity is investigated. Three types sensitive chiral fiber gratings are studied: (1) long-period (CLPGs) resonantly couple core modes to copropagating cladding optical modes, (2) nonresonant intermediate-period (CIPGs) scatter light out the core, and (3) resonant short-period (CSPGs) reflect within core. Each these interacts only with circularly polarized same handedness...
Examples of adiabatic modification optical fiber parameters while maintaining single-mode propagation are discussed in the paper. It is found that variation polarization mode enables efficient coupling a PM supporting linearly polarized modes and chiral circularly or elliptically
Polarization conversion and scattering are synchronized in birefringent fiber twisted with nonuniform pitch so that one incident polarization eigenstate is strongly scattered while the other freely transmitted. This makes possible a broadband linear polarizer.
