4. 2. VCSEL Techniques for Wavelength-Multiplexed Optical Interconnects

   Author : Mehdi Jahed; Chalmers tekniska högskola; []
   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

5. 3. 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.

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

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