GaAs based LD epitaxy wafer, which can generate stimulate emission, is widely used for fabricating laser diode since the superior GaAs epitaxial wafer properties make the device a low energy consumption, high efficiency, long lifetime and etc. In addition to gallium arsenide LD epi wafer, commonly used semiconductor materials are cadmium sulfide (CdS), indium phosphide (InP), and zinc sulfide (ZnS).

About LD Epitaxy Wafer Applications & Market

The applications of GaAs based LD epitaxy wafer in the laser field can be divided into VCSELs and non-VCSELs. The current GaAs based LD epitaxy applications mainly lies in VCSELs. VCSEL (Vertical Cavity Surface Emitting Laser), based on GaAs materials, is mainly used for face recognition. It is expected to have a high growth rate in the future. EEL (Edge Emitting Laser) is a non-VCSEL device, mainly used in the field of automotive lidar, and the demand is expected to increase with the expansion of the driverless car market.

The GaAs substrate used in the laser field requires high technical indicators, and the unit epitaxial wafer price is significantly higher than that of other fields. The future LD epitaxial market space can be expected. Laser applications are the most sensitive to dislocation density. There is a high requirement for the GaAs substrate materials in laser applications. Therefore, the higher requirement is put forward on LD epitaxial wafer manufacturers and LD epitaxial wafer process. At present, the near-infrared band (760~1060 nm) semiconductor laser based on GaAs substrate has the most mature development and the most widespread application, and it has already been commercialized.


The Chinese government has announced new limits on the exportation of Gallium materials (such as GaAs, GaN, Ga2O3, GaP, InGaAs, and GaSb) and Germanium materials used to make semiconductor chips. Starting from August 1, 2023, exporting these materials is only allowed if we obtains a license from the Chinese Ministry of Commerce. Hope for your understanding and cooperation!
