Design of few mode optical fiber and few mode optical system for space division multiplexing applications

Abstract

The modern communication world is realistic with higher speed of newlinedata transmission. In recent years, as the technology that way for bonding the newlinenetwork, it would require for higher bandwidth support in order of THz. The gap newlinebetween information data center and the user compact well meshed with the newlinemaximum guarantee of accessing data through light transmission and guiding newlinemedium. It is commonly known as fiber optical cable. The initial development of newlinefiber cable has relied on telecommunication industries and its unique properties newlinediverge in various applications such as medical sensing, nonlinear signal newlineprocessing, astrophotonics, silicon photonics and integrated optics which also newlineincludes lensing applications. Of course, it is ubiquitous for telecommunication newlineapplications. The various form of fiber reconfiguration according to its refractive newlineindex profile makes the significance thought of optical guiding medium. newlineDepending upon the requirement and attempt to retain over the length of optical newlinecable, the features are enhanced with reforming fiber refractive index profile and newlinefew types are called as Dispersion Compensation Fiber (DCF), Dispersion newlineDecreasing Fiber (DDF), Dispersion Flattened Fiber (DFF), Dispersion Shifted newlineFiber (DSF), Ultra-Flattened Dispersion Fibers (UFFs), Highly Nonlinear Fiber newline(HNLF) and Multitrench Fiber (MTF). The supportive modulation and multiplexing scheme are also developed and referred as Wavelength Division Multiplexing (WDM), Polarization Division Multiplexing (PDM) etc. The demand over the data access is still increased upon the rapid increases of user. The tradeoff between the higher data rate and dense of users is very crucial tomaintain with the existing multiplexing scheme. It is due to the complex newline newline
