  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.

    Abstract : According to the 2018 Ethernet Roadmap projections, the requirements for high speed links keep increasing every year, always keeping an eye on the energy per bit consumption of the communication system. The Ethernet requirements are estimated to reach 1Tbps by 2022-2025. READ MORE

  3. 3. Simulation of Traveling Wave Electroabsorption Modulators for Phase Modulation

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

    Author : Prasanna Ramaswamy; [2012]
    Keywords : ;

    Abstract : Electro-Absorption Modulators (EAMs) have been instrumental in achieving ultrafast modulation speeds of over 100 Gb/s, and in particular, segmented Travelling-Wave (TWEAMs) designs offer excellent compatibility with standardmicrowave technology due to their characteristic impedance being closer to 50. The TWEAM device fabricated as part of the European Project HECTO, has been succesful is field trials at 112 Gb/s using On-Off Keying (OOK). READ MORE
