Epi Wafer untuk Laser Diod

Epi Wafer untuk Laser Diod

Wafer epitaxy LD berasaskan GaAs, yang dapat menghasilkan rangsangan pelepasan, digunakan secara meluas untuk membuat dioda laser kerana sifat wafer epitaxial GaAs yang unggul menjadikan peranti ini penggunaan tenaga rendah, kecekapan tinggi, jangka hayat yang lama dan lain-lain. Selain wafer LD epi gallium arsenide , bahan semikonduktor yang biasa digunakan adalah kadmium sulfida (CdS), indium fosfida (InP), dan zink sulfida (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.
