Tuttle Capital Management has launched an actively managed ETF designed to give investors focused exposure to the fast-growing photonics industry.

The Tuttle Capital Pure Play Photonics ETF began trading on Friday as demand for AI infrastructure continues to shift toward high-speed optical networking technologies.

Key Features Of FOTO

The fund targets exposure across five major photonics industry layers:

Lasers

Optical transceivers

Silicon photonics

Specialty wafers such as indium phosphide

Foundries and capital equipment

Under normal market conditions, at least 80% of net assets will be invested in companies directly tied to photonics.

Eligible companies generally must derive at least 50% of revenue or operating profits from photonics-related products or services.

The strategy may also include early-stage, pre-revenue, or newly public photonics-focused firms expected to meet those thresholds over time.

According to TrendForce data from December 2025, Nvidia's ( NVDA ) capacity lock-ins with top EML laser suppliers have pushed optical transceiver lead times beyond 2027, contributing to a global supply shortage.

NVIDIA ( NVDA ) has integrated co-packaged optics into its Blackwell GPU platform for chip-to-chip interconnects.

Alphabet disclosed that its Jupiter data center network has deployed more than one million optical transceiver ports.

Amazon Web Services said its Trainium2 AI chip uses photonic I/O to improve interconnect bandwidth.

Microsoft ( MSFT ) has highlighted optical networking in its multi-year AI infrastructure spending plans.

Major semiconductor foundries have also announced silicon photonics manufacturing capacity expansions.

AI Constraints Evolve

Matthew Tuttle, CEO and CIO of Tuttle Capital Management, said the AI sector has gone from compute shortages in 2021 to memory limitations in 2023, and now toward the "highway between chips."

He added that photonics technology is rapidly moving from long-haul networking applications directly into data centers, chip packages, and eventually onto silicon dies.

Unlike passive thematic ETFs, FOTO is actively managed to allow flexibility as the photonics ecosystem evolves. The fund focuses primarily on small- and mid-cap companies involved across multiple layers of the photonics supply chain and applies a strict pure-play revenue screen to maintain concentrated exposure to the industry.

Hyperscalers Jack Up Spending

The FOTO launch comes as hyperscalers ramp up spending on AI data centers, with capital expenditures from the four largest U.S. cloud providers estimated at roughly $610 billion annually.

Industry experts increasingly view data-transfer infrastructure as the next major bottleneck in the AI buildout, driving a transition from traditional copper interconnects to photonics-based systems that move data using laser light through fiber-optic networks.

Photonics investments are increasingly appearing in hyperscalers' publicly disclosed capex plans, product roadmaps, and infrastructure expansion announcements, the press release noted.

For instance, Nvidia Corp ( NVDA ) has integrated co-packaged optics into its Blackwell GPU platform for chip-to-chip interconnects, while Alphabet, Inc ( GOOG ) disclosed that its Jupiter data center network has deployed more than one million optical transceiver ports.

Amazon.com, Inc.’s AWS said its Trainium2 AI chip uses photonic I/O to improve interconnect bandwidth, and Microsoft Corp ( MSFT ) has highlighted optical networking in its multi-year AI infrastructure spending plans. Major semiconductor foundries have also announced silicon photonics manufacturing capacity expansions.
