  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. Active Phase Compensation in a Fiber-Optical Mach-Zehnder Interferometer

    University essay from Linköpings universitet/Informationskodning

    Author : Joakim Argillander; [2020]
    Keywords : phase stability; interferometer; quantum key distribution; fpga; automatic control; fasstabilitet; interferometer; kvantnyckeldistribution; fpga; reglerteknik;

    Abstract : This thesis investigates the phenomena of phase stability in a fiber-optical MZI (Mach-Zehnder Interferometer). The MZI is a key building block of optical systems for use in experiments with both continuous-wave light and with single photons. READ MORE

  4. 3. Physical modeling of optical modulators for optical link analysis : Optical link analysis in silicon photonics technologies

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Daniele Poggi; [2019]
    Keywords : Silicon photonics; physical modeling; ring modulator; electro-absorption modulator; optical modulator; optical link system; power consumption; Kiselfotonik; fysisk modellering; ringmodulator; elektroabsorptionsmodulator; optisk modulator; optiskt länksystem; strömförbrukning;

    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

  5. 4. Experimental Implementation of a Fiber Noise Cancellation System for Slow Light Laser Locking

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Partikel- och kärnfysik

    Author : Alexander Bengtsson; [2017]
    Keywords : Optical Fibers; Fiber Noise Cancellation; Laser Stabilization; Slow Light Laser Locking; Technology and Engineering;

    Abstract : An electromagnetic wave propagating through an optical fiber is sensitive to external disturbances, such as mechanical vibrations and temperature and pressure fluctuations, which add phase noise onto the wave. For high-precision frequency-based applications this phase noise has to be removed. READ MORE
