A 4 x 28 Gbit/s optical receiver arrayJochen VerbruggheDepartment of Information Technology, Ghent UniversitySupervisor(s): Jan Vandewege, Johan Bauwelinckhe Internet is expanding at breakneck speed. In four years from now, the Internet’s traffic vol-ume will be so large that every five minutes it will be equivalent to downloading every movie evermade. The increase in mobile device usage (tablets, smartphones, wireless modems and the like),the proliferation of Wi-Fi hotspots and the ever increasing transfer of video data requires massivebandwidth, both wireless and wired. This places a tremendous burden on the current communi-cation technologies. The Internet backbone has since long been using optical technology, as domedium-sized regional access networks. Fibers suffer relatively little attenuation, allowing themto cover long distances without repeaters. Typically many fiber optic cables are bundled togetherto increase the capacity.In order to increase data rates, multiple data streams have been multiplexed together on one opticfiber. Each stream is assigned it’s own carrier on which the data is modulated. This frequency-division multiplexing scheme has already been successfully applied to wireless communication.However, due to the virtually unlimited bandwidth of the fiber, the potential increase in data ratesin the optical domain is much larger.This research focuses on the development of an optical receiver array for 4 channels, each of-fering a data rate of 28 Gbit per second. Hence, more than 100 Gbit per second can be processedby a single receiver chip. Each channel is allowed, on average, a single bit error per trillion (1E12)received bits, at a received optical power of -15 dBm. Special attention is given to low powerconsumption (90 mW per channel). Due to the integration of multiple channels in one IC, areaconstraints come into play and inter channel interference must be accounted for. As of now, a firstversion of the chip has been designed, verified by simulation and sent out for manufacturing andpackaging. A test bed is being developed to evaluate the performance.—————————————————–Research funded by a Ph.D grant of the Agency for Innovation by Science and Technology (IWT) and theEU-funded FP7 ICT-project C3-PO.
