# OpenLight

> OpenLight is a Goleta, California silicon photonics company building the world's first open silicon photonics platform with integrated lasers. Spun out of Juniper Networks in 2022, it licenses a validated process design kit (PDK) and designs custom PASICs - photonic application-specific integrated circuits - that combine lasers, modulators, amplifiers and detectors on a single chip for AI data centers, datacom, telecom, LiDAR and quantum computing.

- **Founded:** 2022
- **Headquarters:** Goleta, California, United States
- **Founders:** Juniper Networks (Parent / spin-out originator (2022)), Synopsys (Founding collaborator (EDA/design tools))
- **Team size:** ~48 employees
- **Products:** PASIC Design Enablement (PDK), PASIC Inhouse Design, PASIC Production, 1.6T / 3.2T PASIC platforms, 400G-per-lane modulators
- **Notable:** Built the world's first open silicon photonics platform with integrated lasers., Raised $84M total across Series A and Series A-1 rounds by April 2026., Demonstrated 400G-per-lane modulators with Tower Semiconductor on commercial silicon photonic wafers.

## Products & services

- **PASIC Design Enablement (PDK)** — A process design kit and component library - integrated lasers, modulators, amplifiers and detectors - that lets customers design their own photonic application-specific integrated circuits, validated at Tower Semiconductor.
- **PASIC Inhouse Design** — Custom photonic IC design, layout and verification services for customers who want OpenLight to build the chip for them.
- **PASIC Production** — Manufacturing of production-ready photonic chips with guaranteed operation, via a foundry ecosystem.
- **1.6T / 3.2T PASIC platforms** — High-bandwidth photonic platforms delivering 1.6 and 3.2 terabits-per-second class connectivity for AI and data-center optics.
- **400G-per-lane modulators** — High-speed silicon photonic modulators demonstrated with Tower Semiconductor as drop-in replacements for 200G designs.
