We designed an optical add/drop multiplexer for orbital-angular-momentum (OAM)-multiplexed data links by taking advantage of the ring-shaped intensity profile of OAM beams. We demonstrated adding/dropping a single OAM beam from three multiplexed OAM beams using liquid-crystal-on-silicon-based diffraction optical elements. For multiplexed OAM beams carrying 100 Gbit/s quadrature phase-shift-keyi...

In order to restore hand function in spinal cord injured people by functional electrical stimnlation of arm nerves, we developed an lllpolar neural cuff type electrode with integrated multiplexer circuit. This circuit reduces the number of necessary interconnection leads to a stimulator from twelve to four. Cable reduction was intended to reduce the risk of cable breakage which is one of the ma...

A 16 × 16 digital microfluidic multiplexer is demonstrated. The device makes use of dual-phase AC activation in a bi-layered electrode structure for actuating microdrops independently. A switching arrangement is employed to localize two out-of-phase AC waveforms in one overlapped region of the two-dimensional multiplexer grid. The superimposed AC waveforms overcome the threshold voltage for mot...

We propose all-fiber mode multiplexer composed of two consecutive LP₁₁ mode selective couplers that allows for the multiplexing of LP₀₁ mode and two-fold degenerate LP₁₁ modes. We demonstrate WDM transmission of 32 wavelength channels with 100 GHz spacing, each carrying 3 modes of 120 Gb/s polarization division multiplexed quadrature phase shifted keying (PDM-QPSK) signal, over 560 km of few-mo...

This paper is concerned with the numerical solution of models for the performance analysis of packet delay and loss in a high speed multiplexer. The multiplexer is taken to be of the ATM (Asynchronous Transfer Mode) type with the goal of providing a large degree of exibility in integrating multi-media traac. We examine a variety of numerical methods for solving these models, including the appro...

We demonstrate a dual-band two-mode (de)-multiplexer based on tapered asymmetric directional coupler (ADC). The working principle of the device relies conversion fundamental transverse electric (TE0) mode to first order (TE1) mode. A phase-matching condition is applied across O- and C-bands broaden operation wavelength device. Measurement performed division multiplexing (MDM) link formed by bac...

We report an all-fiber mode division multiplexer formed with cascaded mode selective couplers with significantly broadened bandwidth potentially spanning S, C and L band. This was achieved by matching the effective refractive indices over a wide wavelength range for the few mode fiber and the single mode fiber used in the coupler. The multiplexer provides high coupling efficiency (>55% for the ...

This paper presents an evaluation of four shallow parsers The interest of each of these parsers led us to imagine a parameterized multiplexer for syntactic information based on the principle of merging the common boundaries of the outputs given by each of these programs. The question of evaluating the parsers as well as the multiplexer came in the foreground with the problem of not owning refer...

The paper proposes architectures of 5:3 compressor designs for low power multiplication purposes. The architecture explores the essence of two transistor multiplexer design and novel two transistor XOR gates for the proposed topology with least number of transistors for logic level implementation. The modified and proposed compressor designs reduce the stage delays, transistor count, PDP (power...
