  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.
