Changelight is building an 8-inch silicon photonics production line and expanding capacity across multiple wavelength bands.
Changelight is the second domestic laser chip name and is behind YJSemi on every axis that could be verified. The two facts worth recording are both forward-looking capacity commitments rather than results. It has a new chip platform planned at 100 million units per year covering multiple wavelength bands, currently still in the capacity ramp phase rather than at volume, and separately an 8-inch silicon photonics production line carrying total investment of RMB 5 billion and expected to begin production in early 2027. That silicon photonics line is the more consequential of the two for this registry, because an 8-inch domestic silicon photonics fab would put China's optical chain a step closer to not needing Tower or GlobalFoundries, and RMB 5 billion is a serious commitment rather than a pilot. Against that, no revenue, profit, customer, shipment figure or 2025 to 2026 dated corporate act for Changelight itself was obtained; everything comes from a single comparative analysis of four domestic optical chip companies rather than from company filings, which is why this is KEEP-WATCH rather than PROMOTE and the scores are provisional. Taxonomy note: same as YJSemi, upstream laser chip fabrication rather than interconnect. Revisit trigger: FY2025 results, any named customer, or confirmation that the 8-inch line remains on schedule for early 2027.
