  1. 1. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

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

    Author : Vidar Flodgren; [2019]
    Keywords : GaN; gallium nitride; nanoscience; material science; ultrafast lasers; Yb Laser; Pharos Laser; titanium sapphire laser; device fabrication; lift-off; gold etching; optical-field-induced currents; modelling; matlab; Physics and Astronomy;

    Abstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE

  3. 2. Design and Performance Evaluation of Resource Allocation Mechanisms in Optical Data Center Networks

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Nikam Vikrant; [2016]
    Keywords : Data Center Networks; Optical Circuit Switching; Routing and Wavelength Assignment; Network Function Virtualization; Virtual Network Function Service Chaining; Datacenternätverk; Optisk kretskoppling; Routing och våglängd uppdrag; Nätverksfunktionen virtualisering; VNF-tjanstekedjning VNF-tjänstekedjor;

    Abstract : A datacenter hosts hundreds of thousands of servers and a huge amount of bandwidth is required to accommodate communication between thousands of servers. Several packet switched based datacenter architectures are proposed to cater the high bandwidth requirement using multilayer network topologies, however at the cost of increased network complexity and high power consumption.

  4. 3. VO2 films as active infrared shutters

    University essay from Institutionen för fysik, kemi och biologi

    Author : Daniel Johansson; [2006]
    Keywords : infrared; shutter; vanadium dioxide; VO2; thermochromic; resistive heating;

    Abstract : An active optical shutter for infrared light (3-5 μm) has been designed, exploiting the phase transition in thermochromic vanadium dioxide (VO2). A spin coating processing route for VO2 films has been adapted to manufacture reproducible depositions onto sapphire (Al2O3) substrates. READ MORE
