21. Longer Wavelength GaAs-Based VCSELs for Extended-Reach Optical Interconnects
Sammanfattning : 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.

22. Design and fabrication of long wavelength vertical cavity lasers on GaAs substrates
Sammanfattning : Vertical cavity surface emitting lasers (VCSELs) are today a commodity on the short wavelength laser market due to the ease with which they are manufactured. Much effort has in the last decade been directed towards making long wavelength VCSELs as successful in the marketplace. LÄS MER

24. Elements of AlGaN-Based Light Emitters
Sammanfattning : The III-nitrides have enabled a range of optoelectronic devices and associated applications of great industrial and societal importance. However, the full potential of the III-nitrides remains to be explored. LÄS MER
25. Short-range Optical Communications using 4-PAM
Sammanfattning : 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.
