  1. 1. Design of a 200Gbps externally modulated laser for opto-electronic integration

    University essay from KTH/Tillämpad fysik

    Author : Tianyu Jiang; [2022]
    Keywords : Optical modulator; Externally modulated laser; Traveling-wave; Electroabsorption; PSPICE; Optisk modulator; externmodulerad laser; Resande-våg; Elektroabsorption; PSPICE;

    Abstract : Segmented traveling wave electro-absorption modulators (TWEAMs) can provide a modulation speed above 100 Gb/s, which is needed in new optical communication networks. In the EU-project TWILIGHT, KTH continues the design work of TWEAMs in the EU-projects IPHOBAC and HECTO with the aim to design a new optical modulator to be integrated with an electronic layer.

  3. 2. Phase Locked Loop using LABVIEW

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Chetan Narashimhamurthy; [2019]
    Keywords : Phase Locked Loop; LABVIEW; wireless communication;

    Abstract : The phase-locked loop is an important concept in the field of wireless communication. PLL:s have wide-ranging applications in many electronic circuits. The history and the basic principle of the phase-locked loop are discussed. READ MORE

  4. 3. A Measurement Platform for Characterization of Quantum Cascade Lasers

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

    Author : Joakim Storck; [2016]
    Keywords : ;

    Abstract : A measurement platform has been built to characterize quantum cascade lasers regrown at KTH by measuring their spectral and electrical properties at room temperature. Since the current source used in this work had a compliance voltage which was too low to get above threshold, an adapter was made to put an external voltage source in series with it, raising the voltage over the laser.

  5. 4. Modeling of HVDC IGBT in Pspice : Serving an ultimate goal for converter station EMC studies

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Jin Yang; [2015]
    Keywords : StakPakTM IGBT module; IGBT behavioral model; Single pulse test circuit; Generation 4;

    Abstract : An IGBT/diode model with more accurate characteristics than simple switchis required to serve for EMC issues from converter valve. The purpose of thismaster thesis is to develop an IGBT and diode model to achieve both accuratetransient behavior and fast simulation time during single pulse switchingtest circuit for the 4:5 kV and 2:0 kA StakPakTM IGBT module.
