On-chip two-mode division multiplexing using tapered directional coupler-based mode multiplexer and demultiplexer.
We demonstrate a novel on-chip two-mode division multiplexing circuit using a tapered directional coupler-based TE(0)&TE(1) mode multiplexer and demultiplexer on the silicon-on-insulator platform. A low insertion loss (0.3 dB), low mode crosstalk (< -16 dB), wide bandwidth (~100 nm), and large fabrication tolerance (20 nm) are measured. An on-chip mode multiplexing experiment is carried out on ...
متن کاملFormation of a planar coarse wavelength-division multiplexer and demultiplexer with reflection volume phase gratings.
A compact configuration for a coarse wavelength-division multiplexer (CWDM) and a coarse wavelength-division demultiplexer (CWDDM) that are based on reflection volume phase gratings is formed. The design and calculated results for four-channel CWDM and CWDDM configurations in the region near 800 nm are presented. Theoretical predictions are experimentally verified with a four-channel CWDDM whos...
متن کاملDesign of Reversible/Quantum Ternary Multiplexer and Demultiplexer
In this paper, we show realization of macrolevel ternary reversible 2-qudit Feynman gate, 3-qudit controlled Feynman gate, and 3-qudit Toffoli gates using ternary reversible 1-qudit gates and 2-qudit Muthukrishnan-Stroud gates, which are theoretically realizable using quantum technology such as liquid ion trap [10]. Then we show the design of ternary reversible multiplexer and demultiplexer usi...
متن کاملDesign and performance of AWG multiplexer / demultiplexer in WDM systems
This paper addresses the design of arrayed waveguide grating (AWG) devices from the viewpoint of –3dB bandwidth and free spectral range. A straightforward numerical method of obtaining the physical dimensions of a real device for given – 3dB bandwidth and free spectral range is presented. The paper assesses also the influence of the –3dB bandwidth of the AWG on the performance of a dense wavele...
متن کاملOrthogonal Frequency Division Multiplexing for Wireless Communications
Orthogonal frequency division multiplexing (OFDM) is a promising technique for high-data-rate wireless communications because it can combat inter-symbol interference (ISI) caused by the dispersive fading of wireless channels. The proposed research focuses on techniques that improve the performance of OFDM based wireless communications and its commercial and military applications. In particular,...
