In order to enable applications such as artificial intelligence (AI) and machine learning in a large scale, a large amount of information needs to be processed very fast. To improve the speed of the computation, not only faster graphical and central processors are required, but also the communication between processors and high bandwidth memories should be fast enough to reduce the latency. Optical interconnect can be a replacement for copper interconnect which is providing larger bandwidth and lower latency.
