InP Substrates

As one of the most important compound semiconductor materials, InP single crystal materials are key materials for the production of InP-based laser diodes (LD), light-emitting diodes (LEDs) and photodetectors in optical communications. These devices realize the emission of information in optical fiber communications, Dissemination, amplification, acceptance and other functions. InP is also very suitable for high-frequency devices, such as high electron mobility transistors (HEMT) and heterojunction bipolar transistors (HBT). Due to its superior characteristics, it is used in optical fiber communication, microwave, millimeter wave, anti- Many high-tech fields such as radiant solar cells and heterojunction transistors are widely used.


OST Photonics offers high quality InP substrates for researchers and industries. There are four types of InP materials for you to choose from: undoped InP, S-doped InP, Zn-doped InP and Fe-doped InP. Crystal size and thickness can be customized according to your requirements.
