OpenLight, a designer of custom application-specific photonic chips, secured $50 million in a Series A extension round. This follows the startup's $34 million Series A funding in August 2025.
OpenLight specializes in building photonic chips tailored to specific applications. The company's $50 million extension round reflects continued investor confidence in its technology platform.
The funding brings OpenLight's total Series A capital to $84 million, marking significant backing for the photonics sector. Photonic chips—which use light instead of electricity for data processing—are increasingly relevant for high-speed computing and datacenter applications.
The rapid follow-on funding indicates strong market demand for custom photonic solutions. Investors are betting on the startup's ability to deliver specialized chips for performance-critical applications where traditional semiconductor approaches face limitations.
OpenLight joins a growing wave of startups addressing the photonics opportunity, particularly as data processing demands accelerate across cloud infrastructure and AI workloads.
