Quintessent Closes $11.5M Seed Round

Facebook X LinkedIn Email
SANTA BARBARA, Calif., March. 18, 2024 — Quintessent, a developer of heterogeneous silicon photonics and quantum dot laser technology, has closed on just over $11.5 million in an oversubscribed seed funding round. According to company CEO and co-founder Alan Liu, the funding will be used to expand the company's staff and accelerate the development of scalable optical interconnects build on the company's multiwavelength comb laser, among other technologies.  

Quintessent seeks to address infrastructure bottlenecks for data centers and computing technologies by implementing advanced materials, device/circuit design, and link architecture in order to reduce power consumption and required component count. The company previously formalized a collaboration with Tower Semiconductor and, last year, the collaborators announced what they claimed to be the first heterogeneous integration of GaAs quantum dot lasers and a foundry silicon photonics platform (PH18DB). This PH18DB platform is targeted for optical transceiver modules in data centers and telecom networks, as well as  emerging applications in artificial intelligence, machine learning, lidar, and other sensors.

Manny Stockman, a partner at Osage University Partners, which led the round, will join Quintessent’s board of directors.

Glossary
quantum dots
A quantum dot is a nanoscale semiconductor structure, typically composed of materials like cadmium selenide or indium arsenide, that exhibits unique quantum mechanical properties. These properties arise from the confinement of electrons within the dot, leading to discrete energy levels, or "quantization" of energy, similar to the behavior of individual atoms or molecules. Quantum dots have a size on the order of a few nanometers and can emit or absorb photons (light) with precise wavelengths,...
quantum
The term quantum refers to the fundamental unit or discrete amount of a physical quantity involved in interactions at the atomic and subatomic scales. It originates from quantum theory, a branch of physics that emerged in the early 20th century to explain phenomena observed on very small scales, where classical physics fails to provide accurate explanations. In the context of quantum theory, several key concepts are associated with the term quantum: Quantum mechanics: This is the branch of...
integrated photonics
Integrated photonics is a field of study and technology that involves the integration of optical components, such as lasers, modulators, detectors, and waveguides, on a single chip or substrate. The goal of integrated photonics is to miniaturize and consolidate optical elements in a manner similar to the integration of electronic components on a microchip in traditional integrated circuits. Key aspects of integrated photonics include: Miniaturization: Integrated photonics aims to...
