Fast, reliable, and secure exchange of information is a must for the modern society and requires access anywhere. The Internet today transmits hundreds of terabits per second, consumes 9% of all electricity worldwide, and grows by 20–30% per year. Emerging technologies for Datacenters experience enormous traffic growth due to the vast amount of data to be stored, transmitted, and processed. Technical and economic challenges arise to keep up the bandwidth density and scalability in Datacenters. Therefore, the community is looking into a cost-efficient solution for short-reach optical interconnects. Currently, the industry is deploying a solution for 400 Gigabit Ethernet links. In my lecture, I will highlight the main challenges and opportunities of using high bandwidth devices to build high-speed communications for Datacenters. I will present the results of experimental studies using intensity modulation and direct detection systems for short-reach optical interconnects. High bandwidth devices allow reducing costs, power consumption, and complexity of parallelism for optical interconnects. Finally, I will discuss the efforts of improving the performance of optical interconnects to build 800 Gigabit Ethernet and 1.6 Terabit Ethernet links for Datacenters. Optical interconnects operating at the highest data rate for each high-speed device are required to confront the growing bandwidth density and scalability in Datacenters.
