  1. 16. Hardware-Efficient WDM/SDM Network : Smart Resource Allocation with SDN Controller

    University essay from KTH/Kommunikationssystem, CoS

    Author : Lida Liu; [2019]
    Keywords : WDM; SDM; SDN; routing and wavelength assignment; large-scale network; hardware resource; WDM; SDM; SDN; routing och tilldelning av våglängd; storskaligt nätverk; hårdvara resurs;

    Abstract : Optical networking has been developing for decades and wavelength-division multiplexing (WDM) is the main technology used to carry signals in fiber-optical communication systems. However, its development has slowed because it is approaching the Shannon limit of nonlinear fiber transmission. READ MORE

  2. 17. Implementation of High-Speed 512-Tap FIR Filters for Chromatic Dispersion Compensation

    University essay from Linköpings universitet/Datorteknik

    Author : Cheolyong Bae; Madhur Gokhale; [2018]
    Keywords : DSP; VHDL; FIR; Digital communication; Optical networks; Chromatic dispersion;

    Abstract : A digital filter is a system or a device that modifies a signal. This is an essential feature in digital communication. Using optical fibers in the communication has various advantages like higher bandwidth and distance capability over copper wires. READ MORE

  4. 19. Construction and Characterization of a Confocal Setup for Functionalization of Light Emitting Diodes and Laser Diodes Using an Amorphous Nonlinear Medium

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Hana Zeneli; [2018]
    Keywords : Characterization; Characterization Microscope; Microscope; Confocal; Amorphous Nonlinear Medium; Laser; Laser Diodes; Infrared Laser; Infrared; Optics; Nonlinear Optics; Nonlinear; White Light Emission; Infrared to White Light; Physics and Astronomy;

    Abstract : A confocal microscope is built to examine molecular powders, and in particular the (PhSn)_4S_6 cluster, that emits white light when irradiated with infrared laser light. The confocal microscope operating at long working distances is assembled and characterized. READ MORE

  5. 20. A Differential Measurement Probe with High Common Mode Rejection

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Björn Franzén; [2018]
    Keywords : Common mode rejection; Fiber-optic measurement probe; Current Sensing; High voltage measurements; Optical isolation; Technology and Engineering;

    Abstract : Measuring signals with high frequency common mode components are typically prone to measurement errors due to low common mode rejection at high frequencies. The purpose of this master thesis is to design a measurement probe that presents sufficient common mode rejection to measure current on high voltage motor drives directly at the switching stage, before filtering.
