Silicon photonics (SiPh) is rapidly becoming one of the most in-demand technologies in optical communications, and that momentum is showing up clearly in the supply chain. LandMark Optoelectronics, an epitaxy manufacturer focused on optical communication applications, says customer demand for SiPh-related products remains strong, but its current production levels still aren’t high enough to meet what customers are asking for.
To close that gap, LandMark Optoelectronics is preparing to spend more on expansion. The company is planning to raise capital expenditure (capex) to about NT$1.315 billion, signaling a bigger push to scale up output and strengthen manufacturing capability as silicon photonics moves further into mainstream deployment.
The expansion is also tied to semiconductor-grade production requirements, including equipment designed to support 6-inch silicon photonics (SiPh) processes. As the market shifts toward larger wafer formats and higher-volume manufacturing, suppliers that can deliver consistent, semiconductor-level quality stand to benefit most.
For the silicon photonics market overall, LandMark’s update is another indicator that demand is outpacing supply in key segments of optical communication manufacturing. With data centers, high-speed networking, and next-generation connectivity driving adoption, manufacturers are under increasing pressure to expand capacity, improve yields, and shorten lead times. LandMark’s planned capex increase suggests the company is moving quickly to capture more of that demand and reduce the production shortfall customers are experiencing.
If this ramp-up proceeds as expected, it could help ease supply constraints in the SiPh ecosystem while positioning LandMark Optoelectronics for stronger growth as silicon photonics continues to expand across high-performance optical communications.
