Analog Coherent Detection for Energy Efficient Intra-Data Center Links at 200 Gbps Per Wavelength

As datacenters continue to scale in size, energy efficiency for short reach (<; 2 km) links is a major factor for networks that may connect hundreds of thousands of servers. We demonstrate that links based on analog coherent detection (ACD) offer a promising path to simultaneously achieving signi...
