P Type , High Purity Single Crystal Indium Phosphide Wafer , 4”, Prime Grade
What is InP wafer?
Indium phosphide is a semiconducting material similar to GaAs and silicon but is very much a niche product. It’s very effective at developing very high-speed processing and is more expensive than GaAs because of the great lengths to gather and develop the ingredients. Let’s take a look at some more facts about indium phosphide as it pertains to an InP Wafer.

InP based lasers and LEDs can emit light in the very broad range of 1200 nm up to 12 µm. This light is used for fibre based Telecom and Datacom applications in all areas of the digitalised world. Light is also used for sensing applications. On one hand there are spectroscopic applications, where a certain wavelength is needed to interact with matter to detect highly diluted gases for example. Optoelectronic terahertz is used in ultra-sensitive spectroscopic analysers, thickness measurements of polymers and for the detection of multilayer coatings in the automotive industry. On the other hand there is a huge benefit of specific InP lasers because they are eye safe. The radiation is absorbed in the vitreous body of the human eye and cannot harm the retina. InP lasers in LiDAR (Light Detection And Ranging) will be a key component for the mobility of the future and the automation industry.
