  1. 1. Design, Fabrication and Analysis of InP-InGaAsP Traveling-Wave Electro-Absorption Modulators

    Författare :Stefan Irmscher; KTH; []
    Nyckelord :fiber-optic communication; modulator; electroabsorption; traveling-wave; InP; broad-band modulation;

    Sammanfattning : External modulators will become key components in fiberoptical communica- tion systems operating at 40Gbit/s andhigher bitrates. Semiconductor electro- absorption (EA)modulators are promising candidates because of their high-speed potential, and their process compatibility with thecorresponding semi- conductor laser light sources.

  3. 2. Study on electroabsorption modulators and grating couplers for optical interconnects

    Författare :Yongbo Tang; Urban Westergren; Dries Van Thourhout; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photonic integrated circuit; optical interconnect; transmission line; traveling-wave; electro-absorption modulator; hybrid silicon evanescent platform; grating coupler; vertical coupling scheme; optical antenna; lag effect; polarization beam splitter; Photonics; Fotonik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Decades of efforts have pushed the replacement of electrical interconnects by optical links to the interconnects between computers, racks and circuit boards. It may be expected that optical solutions will further be used for inter-chip and intra-chip interconnects with potential benefits in bandwidth, capacity, delay, power consumption and crosstalk.

  4. 3. High-speed optical modulators based on intersubband transitions

    Författare :Petter Holmström; KTH; []
    Nyckelord :;

    Sammanfattning : Optical modulators are essential components in high speedoptical communication. They are employed to circumvent theinherent speed limitations of direct modulated semiconductorlasers, and may also extend the transmission distance onoptical fibers by providing optical pulses with lowerchirp.
