Silicon PICs Company Scintil Photonics Raises $58M
GRENOBLE, France, Sept. 9, 2025 — Scintil Photonics, a developer of heterogeneous integrated photonics technology for AI infrastructure, has completed a $58 million series B funding round. The company said that it plans to use financing from the round, which included participation from NVIDIA, to expand its business and scale internationally.
According to company CEO Matt Crowley, the financing comes as Scintil begins volume production of its LEAF Light light engine, a dense wavelength division multiplexing (DWDM)-native light engine aligned with next-generation co-packaged optics (CPO). The single-chip solution monolithically integrates distributed feedback (DFB) lasers on silicon PICs. It delivers 6.4 Tbps/mm edge bandwidth density, at roughly one-sixth the power consumption of conventional pluggable solutions, the company said. LEAF Light technology builds on Scintil's proprietary Scintil Heterogeneous Integration Photonics (SHIP) process technology.
"With LEAF Light entering high-volume production, we’re expanding from our base in Grenoble into the international markets, including the U.S., to support the world’s most advanced AI factories," Crowley said. Scintil Photonics is headquartered in Grenoble, France, and has offices in Canada and the U.S. The company is establishing a U.S.-based presence to serve hyperscale and AI infrastructure partners more directly, it said. It is actively hiring across engineering, operations, and customer integration roles to support increasing product demand and enable high-volume delivery.
Yotta Capital Partners and NGP Capital, led the funding, with participation from NVIDIA and BNP Paribas Développement, alongside existing investors Supernova Invest, Bpifrance Digital Venture, Innovacom, Bosch Ventures, and Applied Ventures ITIC Innovation Fund.

A 2018 spinout of CEA-Leti, Scintil Photonics unveiled its fully chip-integrated 100-GHz DFB comb laser source in 2023. The company's light sources are fabricated on Tower Semiconductor's high-volume base PH18M silicon photonics foundry technology.

Glossary
- 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:

- dense wavelength division multiplexing
- Dense wavelength division multiplexing (DWDM) is an optical communication technique used to increase the data-carrying capacity of optical fiber networks by simultaneously transmitting multiple optical signals, each at a different wavelength, over a single optical fiber. DWDM enables the transmission of a large number of independent data channels or signals over the same fiber, effectively multiplying the network's capacity without the need for additional physical fibers.
In a DWDM system,...
- artificial intelligence
- The ability of a machine to perform certain complex functions normally associated with human intelligence, such as judgment, pattern recognition, understanding, learning, planning, and problem solving.
- photonic integrated circuit
- A photonic integrated circuit (PIC) is a compact and integrated device that incorporates multiple photonic components and functions on a single chip, similar to the way electronic integrated circuits (ICs) integrate various electronic components. The goal of a photonic integrated circuit is to manipulate and control light signals for applications in optical communication, sensing, signal processing, and other photonic technologies.
