Photonics integrated circuits (PICs), a broader and more accurate term than "silicon photonics," are now being deployed by hyperscalers to bypass power and bandwidth ceilings in ways fundamentally different from the telecom shift from copper to fiber, both technologically and economically.
There are two factors accelerating the transition to integrated photonics and pushing the surge in commercialization efforts of these technologies: technological performance limits and market pressures.
The physical limits of electronics-based lithography and packaging constrain progress along Moore's Law. Evolving lithographic processes increase feature density. However, forcing more electrons through smaller volumes increases heat and electrical interference. Using photons instead of electrons to carry information reduces these effects.
As global economic conditions shift toward AI-driven productivity and cross-border data flows, data movement–its cost, energy footprint, and scalability–is emerging as the structural bottleneck. This positions integrated photonics and optical interconnects as critical enablers of the next phase of digital infrastructure. Data centers are the economic ground zero of this transition, driving capital investment toward optical architectures. Integrated photonics offers a step change in power efficiency and throughput, enabling hyperscale expansion without proportional energy growth–aligned with rising energy costs, emissions scrutiny, and the geopolitical race to secure digital supply chains. The investment implication is clear: Over the coming cycle, capital is likely to favor companies that can commercialize optical interconnects, integrated photonic chips, and energy-efficient data center infrastructure.
The secret driving force
While these two factors are driving momentum, an often-overlooked third factor is coming more into play: security. It's clear that software-only approaches to security are increasingly insufficient. For greater trust, technology must be built into the communication infrastructure, not layered on top. Embedded photonic channels reduce attack surfaces by eliminating conductive paths that can be tapped. Integrated photonics can merge optical signaling and encryption, such as true random-number generation, at the hardware layer.
Differences between the telecom boom (and bust) and the PIC explosion
When ushering in new technologies, it's common to look at past widespread industry transitions to anticipate market needs, technologically and financially. Telecommunications moved from copper to fiber decades ago. While ICs appear to be on a similar path, the differences are significant.
Different 'killer apps'
Telecommunications adopted fiber to support, long-haul, high-data-rate transmission over thousands of kilometers, but that expansion was driven by anticipated, rather than proven, demand, and it crashed when the dot-com bubble burst. In contrast, integrated photonics is driven by real, surging demand from AI and blockchain systems–services we already struggle to support. Unlike the telecom era, there is no slowing of demand for services we already struggle to meet.
Same building blocks, different scales
Telecommunications and integrated photonics use the same building blocks–waveguides, light sources, modulators, and photodetectors–but shrinking these components from micron scale to nanometer scale introduces fundamentally different physics, fabrication methods, and integration challenges:
Waveguides: Telecom systems guide light through optical fibers; PICs guide light through lithographically patterned waveguides or, in some cases, free-space paths on-chip.
Light sources: Telecom lasers are discrete, temperature-controlled modules coupled via bulk optics. PIC lasers (typically InP) are integrated on-chip, reducing size, power, and system complexity.
Modulators: Telecom modulators are discrete LiNbO₃ or InP devices with centimeters-long fiber pigtails and couplers. PIC modulators are patterned directly onto silicon, enabling compact, energy-efficient, densely multiplexed modulation.
Photodetectors: Telecom receivers use discrete InGaAs detectors paired with off-chip transimpedance amplifiers via fiber. PIC photodetectors (generally Ge) are co-integrated with amplifiers, waveguides, and logic for high-density, low-loss signal conversion.
Because the major challenge for PICs is developing lithographic and packaging processes that can manufacture these components efficiently at scale with acceptable yield and alignment tolerances, the industry must evolve manufacturing capabilities. Fortunately, CMOS fabrication tools and processes already provide a strong foundation for this transition.
The investment landscape for the PIC market
The PIC sector combines long development cycles with high capital requirements, but it is driven by structural, non-optional demand from hyperscalers, financial institutions, and decentralized networks. Investors with patient capital and an understanding of hardware scaling economics are positioned to benefit as optical interconnects and photonic security become foundational layers of digital infrastructure.
In looking at where capital investment is concentrating, analysis points to packaging and interconnect innovations, as well as photonics-based security stacks. These segments map directly to the main pain points driving adoption: energy-efficient interconnects and hardware-level cryptographic resilience.
However, investors must be realistic about horizons and capital intensity. PIC startups have materially longer development arcs–typically eight to 14 years to scale–and require between $40 million and $150 million before meaningful revenue inflection. Median time to exit for photonics startups is roughly about nine years, and the estimated failure rate ranges between 40% and 60% over 10 years, though observed shutdowns appear lower due to survivorship bias and unpublicized wind-downs.
The U.S. economy had 35–50 viable integrated-photonics companies founded between 2015 and 2025 across Si, SiN, InP, and LNOI platforms.
Based on historical benchmarks and sector comparisons, most of these early-stage startups (secure photonic hardware, fintech/exchange pilots) range between a valuation of $10 million and $20 million pre-money, as opposed to the growth-stage startups (telecom/financial deployments, quantum-ready pilots) that fall in the range of $30 million to $70 million pre-money. On average, about $189 million is raised by such startups before they can take the exit route, with the highly successful exits raising between $22.5 million and $450 million. PIC companies that ultimately succeed typically raise between $175 million and $200 million before exit.
High-value outcomes consistently align with companies that have large total addressable markets and system-level platforms such as coherent optics and advanced sensing with broad application. Lower-value exits (<$200 million) tend to occur in niche PIC architectures such as component-only product strategies.
Exit dynamics have now changed and SPAC channels have collapsed, removing the previously inflated pathway used by several optics companies in 2020–2021. Staged acquisitions are increasingly prevalent as corporations acquire PIC teams for integration capability rather than full product portfolios.
