  3. 2. 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.
