Everbright Photonics (688048): Everbright ramps EML and CW laser capacity to meet AI optical-networking demand

Overview

This chairman-visit note examines Everbright Photonics’ role in laser components for optical networking, automotive applications and AI data centers. Goldman Sachs says management’s positive demand outlook and capacity plans align with its constructive industry view, while noting that Everbright itself is not covered.

Core views

Goldman Sachs hosted Everbright Photonics’ chairman in Suzhou on September 7 during its China AI Tour. Management remained positive on optical-networking end-market demand and said continuing customer penetration, together with capacity expansion, should position the company to capture growth. Goldman Sachs says this supports its own positive view of optical networking, where demand and a technology shift toward higher speed, lower power consumption, greater density and bandwidth, and lower latency are driving specification upgrades and, in its view, healthy competition. Everbright is an integrated device manufacturer producing high-power laser chips based on GaAs, GaN and InP. It is expanding beyond industrial applications into automotive and AI data-center optical networking. In automotive, GaAs VCSEL is used in LiDAR, and management identifies blind-spot LiDAR for smart driving as a potential key driver in 2027E. In optical networking, the company’s offering spans EML, CW lasers and VCSEL, with capacity expansion intended to support the AI data-center trend. Management described a sharp optical-networking capacity ramp: total monthly EML and CW laser capacity is expected to increase by triple digits in 3Q26 versus 1H26, followed by another triple-digit increase in 4Q26 versus 3Q26. Everbright produces InP epitaxial wafers in-house. Management noted that equipment supply is tighter for the InP-related front end than for back-end processes, but said prior preparation had secured the necessary front-end equipment. It added that back-end capacity is easier and faster to expand, with roughly three months sufficient to double capacity. For 2027E, management expects capacity to be weighted toward EML rather than CW lasers, spanning 100G and 200G EML, with 100G accounting for the majority. The company has already mass-produced 100G EML; 200G EML shipment ramp is expected in 2027E and depends on how quickly customers move to 1.6T optical modules. CW lasers are currently mainly 70mW and 100mW products, while a 400mW product is under development. Separately, 100G VCSEL is already shipping, although volume expansion depends on customers’ CPO ramp and their choice of materials, including VCSEL and Micro LED, for short-distance connections.

Analysis framework

The note combines management commentary from the chairman visit with an industry supply-demand view. It traces how AI data-center demand and optical-module specification upgrades drive demand for laser components, then assesses Everbright’s product roadmap, manufacturing bottlenecks, capacity-expansion speed and customer-adoption dependencies.

Methodology notes

• Industry AnalysisSupply-demand framework

  Optical-networking demand matched against laser production capacity and equipment availability.

  The report links growing AI data-center and optical-networking demand to Everbright’s planned EML and CW capacity increases, while considering constraints in InP-related front-end equipment.

• Industry AnalysisUpstream-Midstream-Downstream Transmission

  Technology migration from AI data centers and optical modules to laser-component demand.

  The report explains how customer migration to 1.6T modules and CPO adoption could translate into shipment demand for 200G EML and VCSEL products.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Everbright Photonics (688048.SH)

  Primary subject; a laser-chip supplier positioned for industrial, automotive and AI data-center optical-networking demand.

  Strengths

  In-house InP epitaxial-wafer production, secured front-end equipment, broad EML/CW laser/VCSEL offering, and rapid back-end capacity expansion.

  Risks

  200G EML shipments depend on customer migration to 1.6T modules; VCSEL volume depends on CPO ramp and materials choices.

Key data

• Laser monthly capacity growthTriple digit in 3Q26 vs. 1H26; another triple digit in 4Q26 vs. 3Q26Management expectation for combined EML and CW laser capacity.
• Back-end capacity expansion timeAround three monthsManagement indicated this period could double back-end capacity.
• EML product status100G mass produced; 200G shipment ramp in 2027EThe 200G ramp depends on the pace of customer migration to 1.6T optical modules.
• CW laser products70mW and 100mW currently; 400mW under developmentManagement’s stated CW laser product progression.
• VCSEL product status100G already in shipmentVolume expansion depends on customers’ CPO ramp and materials choices for short-distance connections.

Impact & implications

The report argues that Everbright’s product breadth and rapid capacity-expansion capability could help it participate in growing AI data-center optical-networking demand. Its ability to convert that opportunity into higher-volume 200G EML and VCSEL shipments remains tied to customer technology migration and adoption.

Risks

• The planned 200G EML shipment ramp in 2027E depends on how quickly customers migrate to 1.6T optical modules.
• VCSEL volume expansion depends on customers’ CPO ramp and their material choices for short-distance connections.
• InP-related front-end equipment remains tighter in supply, although management said its own equipment needs were secured.

What to watch

• Whether the company delivers the stated triple-digit sequential capacity increases in 3Q26 and 4Q26.
• The pace of customer migration to 1.6T optical modules and resulting 200G EML demand.
• Customer CPO adoption and material choices affecting 100G VCSEL volume.
