Harvard University's school of engineering has an announcement. "For all the recent advances in integrated lithium niobate photonic circuits — from frequency combs to frequency converters and modulators — one big component has remained frustratingly difficult to integrate: lasers..." Long haul telecommunication networks, data center optical interconnects, and microwave photonic systems all rely on lasers to generate an optical carrier used in data transmission. In most cases, lasers are stand-alone devices, external to the modulators, making the whole system more expensive and less stable and scalable.

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences collaborated with industry partners to develop the first fully integrated high-power laser on a niobate chip.

A graduate student at SEAS and the first author of the study said that integrating high-performance plug-and-play lasers would reduce the cost, complexity, and power consumption of future communication systems.
