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

    Author : Tamas Lengyel; Chalmers tekniska högskola; []
    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.

  5. 23. VCSEL Cavity Engineering for High Speed Modulation and Silicon Photonics Integration

    Author : Emanuel Haglund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed modulation; on-chip laser source; vertical-cavity surface-emitting laser VCSEL ; semiconductor lasers; optical interconnects; large signal modulation; laser dynamics; heterogeneous integration; vertical-cavity silicon-integrated laser VCSIL ; silicon photonics;

    Abstract : The GaAs-based vertical-cavity surface-emitting laser (VCSEL) is the standard light source in today's optical interconnects, due to its energy efficiency, low cost, and high speed already at low drive currents. The latest commercial VCSELs operate at data rates of up to 28 Gb/s, but it is expected that higher speeds will be required in the near future. READ MORE

  7. 25. Contacts and Interconnects for Germanium-based Monolithic 3D Integrated Circuits

    Author : Lukas Jablonka; Zhen Zhang; Shi-Li Zhang; Fabrice Nemouchi; Uppsala universitet; []
    Keywords : Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : Three-dimensional integrated circuits have great potential for further increasing the number of transistors per area by stacking several device tiers on top of each other and without the need to continue the evermore complicated and expensive down-scaling of transistor dimensions. Among the different approaches towards the realization of such circuits, the monolithic approach, i. READ MORE
