Colorado-Based Polaris Electro-Optics Raises $50M in New Funding

The round also saw participation from Socratic Partners, Cambium Capital, Knollwood, Hudson River Trading, Koch Disruptive Technologies, M Ventures, Rhapsody Venture Partners, Buff Gold Ventures, and Blue Sky Capital.

The company plans to use the funding for portfolio expansion, volume scale-up, product tapeouts, qualification and engineering hiring across its two sites.

What is Polaris Electro-Optics?

Polaris Electro-Optics develops high-speed electro-optic modulators for AI, datacom and telecom infrastructure.

Its FenGlass platform uses a proprietary ferroelectric nematic glass material integrated directly onto silicon photonic wafers after they leave the foundry. The process uses standard manufacturing methods and does not require poling.

The platform is designed to support high-speed data movement while addressing bandwidth and energy challenges in AI infrastructure. Polaris says FenGlass can reach 400 Gbps per lane with sub-volt drive voltages, a compact footprint and high linearity.

The technology is being developed for applications including pluggable optical modules, near-packaged optics, co-packaged optics and coherent scale-across architectures.

How Much Funding Has Polaris Electro-Optics Raised?

Polaris Electro-Optics has raised $50 million in its latest funding round.

The company’s earlier funding amount and previous rounds were not provided.

Who Invested in Polaris Electro-Optics’ New Funding Round?

Walden Catalyst Ventures led the funding round.

Other participating investors include:

• Socratic Partners
• Cambium Capital
• Knollwood
• Hudson River Trading
• Koch Disruptive Technologies
• M Ventures
• Rhapsody Venture Partners
• Buff Gold Ventures
• Blue Sky Capital

Why the Funding Matters

Polaris Electro-Optics will use the funding to expand its product portfolio, increase production volumes, support product tapeouts and qualification, and hire additional engineers across its two company sites.

The company has demonstrated and independently verified 400 Gbps per lane modulation using FenGlass. It has also completed Telcordia reliability testing, and validated compatibility with standard solder reflow.

These capabilities are being developed for optical interconnect applications using flip-chip, 2.5D and 3D packaging.

Who founded Polaris Electro-Optics?

Polaris Electro-Optics was founded in 2021 by Cory Pecinovsky.

The company is headquartered in Carlsbad, California.

Market and Business Growth

Polaris has demonstrated 400 Gbps per lane modulation with its FenGlass platform and says the technology can be tuned across product generations, from 200G per lane to 400G and toward 800G.

The company is partnering with optical module makers, hyperscalers and major cloud infrastructure providers to develop solutions for different optical interconnect architectures.

What Happens Next?

Polaris Electro-Optics is targeting its first product launch for 2027.

The company will use the new funding to expand its portfolio, scale volumes, complete product tapeouts and qualification, and grow its engineering teams.

"The industry doesn't have a speed problem or a manufacturing problem, it has both at the same time, and every existing platform solves only one," said Morten Nissov, CEO of Polaris Electro-Optics. "Our FenGlass platform enables 400G per lane and beyond while staying inside a standard CMOS silicon photonics flow.

"New electro-optic materials have been failing the same test for decades: they work in the lab but fail in the fab," said Andy Kau, Partner at Walden Catalyst Ventures. "What convinced us about Polaris is that FenGlass goes onto a finished silicon photonics wafer using processes a contract manufacturer already runs.
