OpenLight Expands Photonic Chip Technology with Silicon Photonics Innovation and Global Growth Plans

The silicon photonics startup space is gaining strong momentum as OpenLight secures an additional $50 million in extended Series A funding, bringing its total funding to $84 million.

The round highlights rising investor interest in advanced semiconductor and photonic chip technology, particularly solutions designed for next-generation data and communication infrastructure.

Strong Investor Backing for Photonic Chip Innovation

The oversubscribed funding round was led by Matter Venture Partners, with participation from new investors including Acclimate Ventures and Catapult Ventures.

Existing backers such as Mayfield, Capricorn Investment Group, Xora Innovation, and New Legacy also joined the round.

The strong investor participation reflects growing confidence in silicon photonics technology and its role in shaping the future of high-speed computing and communication systems.

Building Next-Generation Photonic Chips

OpenLight specializes in designing application-specific photonic chips, known as Photonic Application-Specific Integrated Circuits (PASICs), often described as the photonic equivalent of traditional ASICs.

The company’s technology enables the integration of multiple optical components on a single chip, including:

  • Integrated lasers
  • Modulators
  • Amplifiers
  • Detectors

These innovations are powered by OpenLight’s Process Design Kit (PDK), which combines indium phosphide and silicon photonics integration.

Scaling High-Speed Data Technologies

With the new funding, OpenLight plans to expand its PDK library of photonic components, including advanced technologies such as:

  • 400G modulators
  • Indium phosphide heterogeneously integrated on-chip lasers
  • Next-generation 1.6T and 3.2T photonic integrated circuits (PICs)

These developments are designed to support ultra-fast data transmission, particularly for data center interconnects and high-performance computing systems.

Open Foundry Model Driving Industry Adoption

OpenLight operates under an open foundry model, licensing its technology and component libraries to semiconductor manufacturers.

According to the company, more than 25 global companies are already using its PDK to design and manufacture photonic integrated circuits (PICs) across various applications.

This collaborative approach is helping accelerate adoption of silicon photonics solutions across the semiconductor ecosystem.

From University Research to Global Semiconductor Platform

OpenLight’s origins trace back to 2008, when its core technology was developed at University of California, Santa Barbara spin-out Aurrion.

The company was later acquired by Juniper Networks in 2016 before being relaunched as OpenLight in 2022, with backing from Juniper and Synopsys.

Accelerating Global Expansion

OpenLight CEO Adam Carter said the new investment will help accelerate the company’s roadmap, expand global sales, and strengthen technical support worldwide.

The company aims to bring heterogeneous photonic integrated circuits into global markets at scale, positioning itself as a key player in the future of semiconductor innovation.

The Future of Silicon Photonics

As demand for faster, more efficient data processing grows, silicon photonics is emerging as a critical technology for powering next-generation infrastructure.

OpenLight’s latest funding round signals strong momentum in the industry and highlights increasing investor confidence in photonic chip innovation as a cornerstone of future computing systems.
