  1. 1. Design and Characterization of SiN-based integrated optical components for Wavelength Division Multiplexing

    Författare :Alexander Caut; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosstalk; silicon nitride.; Mach-Zehnder interferometers; polarization; grating couplers; insertion loss; power splitters; arrayed waveguide gratings; silicon photonics;

    Sammanfattning : To follow the trend of the data traffic and to limit the size of the hyperscale data centers, communication solutions offering small footprint, low cost and low power consumption are needed. Optical interconnects used in data centers are mostly short reach (approximately 100 m) based on GaAs-based 850 nm vertical-cavity surface emitting lasers (VCSELs) and OM4 multimode fibers (MMF).

  4. 3. Applications of monolithic fiber interferometers and actively controlled fibers

    Författare :Patrik Rugeland; Fredrik Laurell; Walter Margulis; Miguel Andrés; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber; fiber Bragg grating; micro-structured fiber; add drop multiplexer; fiber interferometer; microwave photonics; temperature sensor;

    Sammanfattning : The objective of this thesis was to develop applications of monolithic fiber devices and actively controlled fibers. A special twin-core fiber known as a ‘Gemini’ fiber was used to construct equal arm-length fiber interferometers, impervious to temperature and mechanical perturbations. LÄS MER
