Indium phosphide has a wide range of applications in semiconductor materials. It can be used to manufacture high-speed electronic devices, optoelectronic devices, microwave devices, etc. In particular, in optical fiber communication technology, indium phosphide is an important material. Optical fiber communication technology is an important part of modern communication technology, and indium phosphide is an important part of optical fiber communication technology. Indium phosphide can be used to manufacture optoelectronic devices such as photoelectric modulators, lasers, and detectors, which play a vital role in optical fiber communication technology.
(1) Indium phosphide has the advantages of high electron peak drift velocity, high bandgap width, and high thermal conductivity. The direct transition band gap of InP is 1.34eV, which corresponds to the band with the smallest transmission loss in optical communication; the thermal conductivity is higher than GaAs, and the heat dissipation performance is better;
(2) Indium phosphide has more advantages than GaAs in device manufacturing. The high current peak-to-valley ratio of InP devices determines the high conversion efficiency of the device; the inertial energy time constant of InP is half that of GaAs, and the working efficiency limit is twice that of GaAs devices; InP devices have better noise characteristics;
(3) Indium phosphide (InP) as a substrate material has the following main applications. Optoelectronic devices, including light sources (LEDs) and detectors (APD avalanche photodetectors), are mainly used in optical fiber communication systems; integrated lasers, optical detectors and amplifiers, etc., are optoelectronic integrated circuits and are essential components of the new generation of 40Gb/s communication systems.
Our products implement the most stringent quality management system. There are strict inspection standards for incoming materials, processes, final inspections, and factory inspections. Strict isolation measures will be adopted for unqualified processing to prevent unqualified products from flowing into the next process. Samples will be provided to customers according to customer requirements for re-inspection.
Vacuum packaging, the packaging quantity can be provided according to customer requirements and packaged separately.
InP should be stored in a dry, ventilated environment, avoid direct sunlight, and stay away from corrosive substances such as acids and alkalis. If the storage environment humidity is high, a desiccant can be placed in the storage container.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
