  1. 1. VCSEL Techniques for Wavelength-Multiplexed Optical Interconnects

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Mehdi Jahed; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon photonic integration; vertical-cavity surface-emitting laser; transverse and polarization mode filter; optical interconnect; distributed Bragg reflector.; wavelengthmultiplexing;

    Abstract : The majority of global data communication is taking place within data centers where data is stored and processed and where the largest part of the power used for global networking is consumed. With the rapidly increasing use of Internet-based applications and services, data centers are equipped with a larger number of servers and switches requiring higher bandwidth connectivity. READ MORE

  2. 2. Short-range Optical Communications using 4-PAM

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Tamas Lengyel; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data communication; vertical cavity surface emitting lasers; 4-PAM; IM DD; NRZ OOK; optical interconnects; short-range fiber optic links; multimode fiber; inter-symbol interference; intensity modulation;

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

  3. 3. Longer Wavelength GaAs-Based VCSELs for Extended-Reach Optical Interconnects

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Ewa Simpanen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reach; high-speed modulation; multi-mode; single-mode; vertical-cavity surface-emitting laser; attenuation; chromatic dispersion; optical interconnect;

    Abstract : Data centers of today are increasing in size and are built to accommodate strong traffic demands while providing sustainably by having clients sharing resources under one roof. Their massive scale puts pressure on the server network topology and has incited a need for data transmission links that are energy efficient and capable of operation at high bit rates with reach up to a few kilometers.

    Abstract : The field of Information and Communication Technologies is witnessing a development speed unprecedented in history. Moore’s law proves that the processor speed and memory size are roughly doubling each 18 months, which is expected to continue in the next decade. READ MORE

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

    University dissertation from Stockholm : KTH

    Author : Tamas Lengyel; []
    Keywords : 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;

    Abstract : 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.
