Modulight's laser components
Semiconductor laser components from chip to finished package
Modulight manufactures laser components in-house, combining semiconductor material growth, wafer processing, laser chip fabrication, packaging, and testing under one roof. Our vertically integrated production enables rapid development, controlled quality, and tailored solutions from individual laser chips to fiber-coupled modules. These include edge-emitting multimode or single-mode diodes, DBR lasers, single-frequency lasers, DFB lasers, VCSELs, VECSELs, fiber lasers, or solid-state lasers – and combinations of any of these. All available across a broad wavelength range from UV to 3000+ nm.
From semiconductor material to tested laser components
Modulight’s vertically integrated manufacturing covers the key stages of laser component production in-house. We grow and process III-V semiconductor materials, manufacture laser structures in our cleanrooms, and package and test the finished devices in our own production facilities.
This integration gives us direct control over critical manufacturing processes and enables fast iteration from device design and prototyping to volume production.

Epitaxial growth: GaAs and InP materials
Modulight grows III-V semiconductor structures based on GaAs and InP, with controlled layer thickness, composition and doping to achieve the optical and electrical properties required for the laser device.
Wafer processing: Laser chip fabrication
Our cleanroom facilities support semiconductor laser processing from prototype development to volume production. Processes include lithography, etching, metallization and grating fabrication for technologies such as Fabry-Pérot, DBR and DFB lasers.
Packaging & testing
Laser chips are packaged and tested in Modulight’s own production facilities. We offer a range of standard and tailored package configurations, including chip-on-carrier, TO-can, butterfly and fiber-coupled packages.
