Coherent Targets $3B Quarterly Revenue by FY2027, Powered by PhotonLink and 6-Inch InP Fab

Coherent (NYSE: COHR), a leader in optical communications and laser technology, recently signaled strong growth prospects during investor communications. Management stated that with the commercial deployment of its next-generation photonic integration platform, PhotonLink, and the accelerated ramp-up of its 6-inch indium phosphide (InP) wafer production line, the company is on track to surpass $3 billion in quarterly revenue for the first time by the end of fiscal 2027. This target represents more than a doubling from current quarterly revenue levels (reported around $1.4 billion) and marks Coherent's transformation from a traditional optical component supplier to a large-scale photonics platform company.

PhotonLink: The Critical Leap from R&D to Commercialization

PhotonLink is Coherent's next-generation co-packaged optics (CPO) and pluggable optical module platform designed for data centers and AI computing clusters. According to the company's technical whitepaper, the platform employs a hybrid silicon photonics and indium phosphide integration scheme, enabling the integration of multiple lasers, modulators, and detectors on a single chip, thereby significantly reducing power consumption and latency. During the recent earnings call, management indicated that PhotonLink has been certified by several hyperscale cloud providers and expects to begin small-volume shipments in the second half of 2025, with volume production ramping up in 2026.

This timeline aligns closely with industry trends. According to LightCounting market research, the global CPO market is projected to exceed $3 billion by 2027, and Coherent, leveraging its long-standing expertise in InP lasers, is well-positioned to capture a significant share. Analysts note that PhotonLink's uniqueness lies in its "optical engine" design, which packages laser arrays and silicon photonic chips on the same substrate, offering a generational advantage in bandwidth density and energy efficiency over traditional pluggable modules.

6-Inch InP Fab: A Dual Lever for Cost and Capacity

Indium phosphide is a critical material for manufacturing high-speed lasers and photodetectors, but its high cost has long been constrained by the small size of 2-inch and 3-inch wafers. Coherent is advancing the world's first 6-inch InP production line. According to the company's engineering vice president at an industry conference, the line completed equipment installation in 2024 and is currently in the process validation phase, with mass production expected by mid-2025.

The transition from 3-inch to 6-inch wafers means approximately a fourfold increase in the number of chips per wafer, with a potential reduction in unit manufacturing costs of over 40%. This cost advantage is crucial for the scalable deployment of PhotonLink, as CPO modules require significantly more lasers than traditional modules, leading to exponential growth in demand for InP chips. Coherent expects that by the end of 2026, the 6-inch line will contribute over 60% of the company's total InP capacity, thereby establishing a solid supply chain foundation for the $3 billion quarterly revenue target.

Financial Trajectory: From $1.4B to $3B

According to the company's financial guidance, quarterly revenue for fiscal 2025 (ending June 2025) is projected to be between $1.35 billion and $1.45 billion, representing year-over-year growth of approximately 8%. To achieve the $3 billion quarterly target by the end of fiscal 2027 (i.e., June 2027), the company would need to more than double its revenue within two years, implying a compound annual growth rate of around 40%.

This growth is expected to be driven by three engines: first, the increasing penetration of PhotonLink in AI data centers, projected to contribute approximately 40% of quarterly revenue by 2027; second, steady growth in traditional telecom and data center optical module businesses, benefiting from the upgrade cycle to 800G and 1.6T modules; and third, a rebound in industrial laser and medical businesses amid macroeconomic recovery. Management emphasized that the $3 billion target is not an "aggressive assumption" but a "conservative estimate" based on secured customer orders and capacity expansion plans.

Industry Competition and Risk Factors

Coherent is not the only company betting on CPO. Giants like Intel, Broadcom, and TSMC are also advancing their own CPO solutions, while traditional competitors such as Lumentum and II-VI (now part of Coherent) are accelerating their InP initiatives. However, Coherent's advantage lies in its vertical integration—from InP substrates to laser chips to module packaging, all done in-house—which provides unique benefits in cost control and iteration speed.

On the risk side, the main concern is technological uncertainty. The standardization process for CPO is still in its early stages, with different customers having divergent interface definitions for optical engines, which could affect PhotonLink's universality. Additionally, if the yield ramp-up of the 6-inch InP line falls short of expectations, it would directly impact cost targets. Management acknowledged during communications that yield is the biggest internal challenge but stated that process improvements have already reduced defect density by over 30%.

Market Reaction and Institutional Views

Following Coherent's announcement of this long-term target, its stock rose over 5% in after-hours trading before pulling back, reflecting market caution toward high-growth targets. According to Bloomberg-compiled analyst estimates, the average Wall Street revenue forecast for Coherent for fiscal 2027 is approximately $11 billion, below the company's implied target of $12 billion (based on $3 billion per quarter). This suggests the company needs to consistently exceed market expectations to achieve this goal.

Several investment institutions noted in research reports that Coherent's InP technology barriers and deep customer relationships provide a credible growth foundation, but achieving $3 billion in quarterly revenue would require capturing about 20% of the global CPO market, which is no easy feat. Morgan Stanley analysts wrote in a report: "We recognize Coherent's technological leadership, but advise investors to monitor actual PhotonLink shipment data in the second half of 2025 to validate its volume ramp logic."

Overall, Coherent's $3 billion target is both a declaration of confidence in its technology roadmap and a bet on the long-term demand for AI computing infrastructure. At this historical juncture where the optical communications industry is transitioning from "pluggable" to "co-packaged," Coherent is attempting to redefine the industry landscape through InP scaling and PhotonLink platformization. Over the next two years, its execution and yield control will be the key variables determining whether this target can be realized.
