1. 11. Optical Interconnects for Next Generation Data Centers : Architecture Design and Resource Allocation

   Författare :Yuxin Cheng; Jiajia Chen; Lena Wosinska; Po Dong; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The current data center architectures based on blade servers and elec- tronic packet switches face several problems, e.g., limited resource utilization, high power consumption and cost, when handling the rapidly growing of data traffic. LÄS MER

3. 12. Advanced modulation formats for short-range optical communications

   Författare :Krzysztof Szczerba; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The demand for faster short range optical links is increasing and simple modulation techniques, such as on-o keying do not scale well to higher data rates, because of the limited bandwidth-distance product of the multimode ber. The industry has responded to this problem by aggregating multiple parallel links operating at lower bit-rate. LÄS MER

4. 13. Broadband Receiver Electronic Circuits for Fiber-Optical Communication Systems

   Författare :Stavros Giannakopoulos; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photodetector; broadband amplifiers; data communication; VCSEL; distributed amplifiers.; receiver front-end; short-haul interconnects; InP DHBT; SiGe HBT; TIA;

   Sammanfattning : The exponential growth of internet traffic drives datacenters to constantly improve their capacity. As the copper based network infrastructure is being replaced by fiber-optical interconnects, new industrial standards for higher datarates are required. LÄS MER

5. 14. Vertical-Cavity Surface-Emitting Lasers: Large Signal Dynamics and Silicon Photonics Integration

   Författare :Emanuel Haglund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; vertical-cavity surface-emitting laser VCSEL .; silicon photonics; high-speed modulation; semiconductor lasers; optical interconnects; laser dynamics; large signal modulation; Heterogeneous integration;

   Sammanfattning : 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. LÄS MER
