The voltage margin of a resistor-logic demultiplexer can be improved significantly by basing its connection pattern on a constant-weight code. Each distinct code determines a unique demultiplexer, and therefore a large family of circuits is defined. We consider using these demultiplexers for building nanoscale crossbar memories, and determine the voltage margin of the memory system based on a p...

The simultaneous capture of imaging data at multiple wavelengths across the electromagnetic spectrum is highly challenging, requiring complex and costly multispectral image devices. In this study, we investigate the feasibility of simultaneous multispectral imaging using conventional image sensors with color filter arrays via a novel comprehensive framework for numerical demultiplexing of the c...

Coarse wavelength division multiplexing (CWDM)-targeted novel silicon (Si)-nanowire-type polarization-diversified optical demultiplexers were numerically analyzed and experimentally verified. The demultiplexer comprised a hybrid mode conversion-type polarization splitter rotator (PSR) delayed Mach–Zehnder interferometric demultiplexer. Si-nanowire-based devices fabricated using commercially ava...

Quantum-dot cellular automata (QCA) are prospective nanotechnology with striking performance to tackle the shortcomings of complementary metal-oxide-semiconductor (CMOS) transistor-based technology such as fabrication dimensions and switching speed. The demultiplexer, a crucial component for design many logic circuits, comprises circuit separating multiplex data into data. demultiplexer is high...

We report on a multifunctional active demultiplexer for optical frequency combs. The proposed technique, based injection locking, combines the functionality of tunable demultiplexer, gain equalizer and an amplifier, all in one device. Validation concept is experimentally demonstrated through simultaneous demultiplexing amplification combs with various free spectral ranges (2.5 to 15 GHz), achie...

An integrated tandem traveling-wave electroabsorption modulators is demonstrated as an optical short pulse generator and demultiplexer for >100 Gbit/s optical time-division-multiplexed systems. Optical pulses of 4.2 ps width at 30 GHz with an extinction ratio in excess of 30 dB are achieved.

Photopolymer materials are widely used in many holographic applications because of their advantages. This paper reviews the various holographic applications which either require the high index modulation including optical demultiplexer, color-display filter, and polarization-selective element, or need the stability and long life such as holographic memory and security card system.

In this article numerical methods used to model photonic devices are presented. In particular, the governing equations describing the problem, the coupling between electrical and optical fields, and the numerical algorithms used for computing solutions are discussed. As a computational example, we present the modeling of a semi-conductor optical amplifier employed as an all-optical demultiplexer.
