Quintessent, a pioneer in heterogeneous silicon photonics and quantum dot laser technology, has closed on just over $11.5 million in an oversubscribed Seed funding round. Osage University Partners (OUP) led the round along with new investors including M Ventures, and joining existing investors Sierra Ventures, Foothill Ventures, and Entrada Ventures.

Quintessent is developing optical connectivity solutions to interconnect compute and switch chips with massively accelerated and power efficient bandwidth across the datacenter. Leveraging multiple innovations spanning materials, device/circuit design, and link architecture, Quintessent technology simultaneously reduces power consumption and required component count while multiplying bandwidth density compared the state of the art.
