PhD Scholarship in Hybrid III-V-on-Si Laser with Ultralow Energy Consumption, Denmark

Motivations: Contemporary computers employ multiple cores to provide better computing performance. Thus, the overall performance of a computer is determined by the speed of interconnects between the cores rather than the already fast core speed. In this chip-level interconnects with increasing importance, low energy consumption is one of key issues. Currently, about 50 % of energy in a processor is used for interconnects. Due to fundamental physical reasons, using light instead of electrons for interconnects at a distance longer than several hundreds of microns is advantageous to solve this energy consumption problem as well as other technological limitations of existing electrical interconnects

Candidates should have a master’s degree in engineering or a similar degree with an academic level equivalent to the master’s degree in engineering. The objectives of the project are to investigate/understand fundamental properties of the new laser structure and to experimentally demonstrate it. For these, this project comprises theory/modeling, device processing in clean room, and characterization. Thus, a successful applicant is preferably expected to have (1) basic understanding on electromagnetism, laser diodes, and optoelectronics, (2) clean room experiences
