In the applications of millimeter and sub‐millimeter wave, the conductivity of metal parts in electronic devices can easily degrade when conventional metals like copper are employed. Furthermore, oxidation may arise when such devices are utilized in severe environmental conditions. To avoid this, conventional conductors such as copper can be coated with other non‐active materials to inhibit this problem...
In order to meet the ultra high speed and ultra long-haul transmission distance in wavelength division multiplexing (WDM) systems, the nonlinear impairment affecting the overall spectral efficiency and system performance should be minimized. This paper proposes a strategy to mitigate the four-wave mixing (FWM) effect in WDM system. The strategy determines the effect of both single and combined effects...
In long-haul transmission systems, optical transmission characteristics are degraded by four-wave mixing (FWM) generated in optical fibers. This paper presents a new approach to reduce the four wave mixing crosstalk based on polarization interleaving is presented. The FWM behavior and the performance of WDM systems were analyzed using the proposed technique. The simulation was performed using different...
Free space optic (FSO) is considered as an attractive option to fiber optic. FSO has the capability to go beyond the limits of fiber optics. However, atmospheric turbulence causes fluctuations in the intensity of the received light signal, impairing link performance. In this paper, we describe a new technique to mitigate turbulence-induced intensity fluctuations, i.e., signal fading (under the effects...
