Reconfigurable optical directed logic circuits (RODLC) aim to perform arbitrary operations using the switch network, in which electrical signals regarded as operands are applied control propagation of light over time, and operation results obtained at output ports network form light. In this paper, a novel RODLC is proposed experimentally demonstrated by utilizing an array with prosperous mode ...

Recently, one of the most commonly discussed applications terahertz radiation is wireless telecommunication. It believed that future 6G systems will utilize this frequency range. Although exact technology telecommunication not yet known, it certain methods for increasing their bandwidth should be investigated in advance. In paper, we present diffractive optical elements division multiplexing wa...

Abstract An optical frequency comb (OFC) frequency-division multiplexing dispersive interference multichannel distance measurement method is proposed. Based on the OFC interference, wide spectrum divided into multiple channels using a wavelength-division multiplexer. Under existing light source and spectrometer, single system can realize six of high-precision parallel absolute measurement. The ...

data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (wdm) technology. the combination of four waves (fwm) is a non-linear effect in the wavelength division multiplex (wdm), when more than two wavelengths of light in a fiber launch will occur. fwm amount depends on the channel, the channel spaci...

This paper presents an overview of the fiber optics and its principles in optical communication network. Fiber nonlinearities are bounded factors for optical communications systems, in specific for wavelength division multiplexing .Among the nonlinearities effect is four-wave mixing ,which is a nonlinear process that generates new frequency components from existing frequency components. FWM is ...
