# SCINTIL Photonics

> SCINTIL Photonics is a Grenoble-based, fabless silicon photonics company building the world's first single-chip, DWDM-native laser source for AI data centers. Spun out of CEA-Leti and founded by Sylvie Menezo, its proprietary SHIP (Scintil Heterogeneous Integrated Photonics) process integrates lasers, modulators and detectors onto one manufacturable chip - powering its LEAF Light light engine for co-packaged optics that promises roughly one-sixth the power consumption of conventional pluggable optics. The company raised a $58M Series B in September 2025 with participation from NVIDIA.

- **Founded:** 2018
- **Headquarters:** Grenoble, France
- **Founders:** Sylvie Menezo (Founder & CTO)
- **Team size:** ~36 employees
- **Products:** SHIP (Scintil Heterogeneous Integrated Photonics), LEAF Light, EVK for LEAF Light
- **Notable:** Developed the industry's first single-chip, DWDM-native light engine (LEAF Light)., Raised a $58M Series B in September 2025 with participation from NVIDIA., Demonstrated ~6.4 Tbps/mm edge bandwidth density at roughly one-sixth the power of conventional pluggable optics.

## Products & services

- **SHIP (Scintil Heterogeneous Integrated Photonics)** — Proprietary process technology that monolithically integrates DFB lasers, silicon modulators, germanium photodetectors and waveguides onto a single chip using BackSide-on-BOX III-V bonding, built on standard silicon photonics fabrication.
- **LEAF Light** — The industry's first single-chip, DWDM-native light engine for co-packaged optics, delivering up to 6.4 Tbps/mm edge bandwidth density at roughly one-sixth the power of conventional pluggable optics, with data transmission exceeding 1 Tbps per fiber.
- **EVK for LEAF Light** — An evaluation kit that lets customers test and qualify the LEAF Light light engine in their own systems.

## Achievements

- Developed the industry's first single-chip, DWDM-native light engine (LEAF Light).
- Raised a $58M Series B in September 2025 with participation from NVIDIA.
- Demonstrated ~6.4 Tbps/mm edge bandwidth density at roughly one-sixth the power of conventional pluggable optics.
- Built SHIP, a foundry-aligned process for monolithic III-V-on-silicon integration.
- Spun successfully out of CEA-Leti to commercialize heterogeneous integrated photonics.

## Latest updates

- **2025-09** — Closed a $58M (€50M) Series B led by Yotta Capital Partners and NGP Capital, with NVIDIA participating, to scale production of its single-chip DWDM light engine and expand hiring in France and the U.S.
