Supporting photonic innovation, from laser chips to optical systems.
Lumi is a China-based supplier of laser chips, packaged laser diodes and photonic components for global B2B customers. We support application-driven sourcing, OEM cooperation and component integration for optical communication, sensing and precision instruments.
Our work connects upstream semiconductor components with practical system requirements—from chip selection and packaging options to optical interfaces and project-specific engineering discussions.
- Based in ChinaGlobal B2B project communication
- Component-focusedLaser & photonic devices
- OEM-orientedRequirements-led cooperation
An engineering-focused supply partner for photonic components.
Photonic projects rarely begin with a part number alone. Customers must align wavelength, spectral behavior, output power, package dimensions, optical coupling and electrical interfaces before a device can be integrated successfully.
Lumi works with OEM customers to clarify those requirements, identify suitable product families and coordinate the appropriate component or packaging route. This supports both catalog sourcing and more specialized development projects.
Practical support across the photonic supply chain.
Different products require different levels of design review and upstream manufacturing cooperation. We align the scope of support with the actual technical and commercial requirements of each project.
Laser Chip OEM & Foundry Support
Project-based cooperation for bare semiconductor laser chips, device requirements and suitable manufacturing pathways.
Laser Diode Packaging
TO-can, butterfly and fiber-coupled configurations to support electrical, mechanical, thermal and optical integration needs.
Design & MPW Coordination
Technical discussions, design support and MPW wafer-service evaluation where the project scope and process route are suitable.
Testing & Characterization
