Data Center Interconnects: Can VCSELs Challenge DFB Lasers?
The increasing demand for higher bandwidth and lower power consumption in data centers is driving the development of optical interconnect technologies. While DFB lasers, traditionally used in long-haul fiber optic communication, offer superior performance, they are expensive and temperature-sensitive. VCSELs, known for their low cost and power consumption, are gaining traction but their wavelength and bandwidth limitations hinder wider adoption. This article explores advancements in VCSEL technology aimed at enhancing their role in short-reach data center interconnects. It highlights Volantis' approach using improved VCSELs and optical interposers to achieve high-efficiency, massively parallel optical interconnects, offering a novel perspective on data center optical interconnect technology.
