Quantum Semiconductor LLC is revolutionizing what silicon can do with light.

Quantum Semiconductor’s technology platform consists of engineered Si-Ge-C superlattices combined with novel semiconductor device architectures that together overcome the limitations imposed by the physical properties of silicon that prevent it from emitting and sensing light outside of the visible range of wavelengths.

We invent and develop our own technology and work with strategic customers to implement our technology platform across a variety of markets and applications. Quantum Semi is privately funded and has received funding from the Defense Advanced Research Projects Agency (DARPA), the National Science Foundation (NSF), and the Office of Naval Research (ONR).

Based in San Jose, California, we are a woman-owned small business developing cutting edge technology.
