  1. 1. Multilevel Modulation and Transmission in VCSEL-based Short-range Fiber Optic Links

    Författare :Tamas Lengyel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IM DD; NRZ OOK; intensity modulation; 3-PAM; inter-symbol interference; Data communication; multimode fiber; vertical cavity surface emitting lasers; 4-PAM; optical interconnects; short-range fiber optic links;

    Sammanfattning : As the demand for ever higher throughput short-range optical links is growing, research and industry associations have shown increased interest in multilevel modulation formats, such as the four leveled pulse amplitude modulation, referred to as 4-PAM. As on-off keying (OOK) persists to be the choice for low latency applications, for example high performance computing, datacenter operators see 4-PAM as the next format to succeed current OOK-based optical interconnects.

  5. 4. Design and Evaluation of Vertical Cavity Surface Emitting Lasers for Microwave Applications

    Författare :Christina Carlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : With the rapid developments of wireless communication networks such as cellular systems for mobile communication and wireless local area networks, as well as developments in radars and defence systems, there is an increasing demand for efficient and cost-effective transmission and distribution of RF and microwave signals. In this respect, fiber optics provide advantages such as low loss, mechanical flexibility, low weight, and natural immunity to electromagnetic interference, enabling densely spaced and electrically isolated transmission paths.
