Indium Phosphide Facts

• Indium phosphide (InP) includes phosphorus and indium and is a binary semiconductor.
• It has a zincblende crystal structure similar to GaAs and almost all the III-V semiconductors.
• It has superior electron velocity due to which it is used in high-frequency and high-power electronics.
• It has a direct bandgap, unlike many semiconductors.
• Indium phosphide is also used as a substrate for optoelectronic devices.
• Molecular weight: 145.792 g/mol
• Melting point: 1062 °C (1943.6 °F)
• It can be used for virtually any electronic device that requires high speed or high power.
• It has one of the longest-lived optical phonons of any compound with the zincblende crystal structure.
• InP is the most important material for the generation of laser signals and the detection and conversion of those signals back to electronic form.

Application in LiDAR systems for the automotive sector and industry 4.0

Widely discussed in the LiDAR arena is the wavelength of the signal. While some players have opted for 830-to-940-nm wavelengths to take advantage of available optical components, companies (including Blackmore, Neptec, Aeye, and Luminar) are increasingly turning to longer wavelengths in the also-well-served 1550-nm wavelength band, as those wavelengths allow laser powers roughly 100 times higher to be employed without compromising public safety. Lasers with emission wavelengths longer than ≈ 1.4 μm are often called “eye-safe” because light in that wavelength range is strongly absorbed in the eye's cornea, lens and vitreous body and therefore cannot damage the sensitive retina).

• LiDAR-based sensor technology can provide a high level of object identification and classification with three-dimensional (3D) imaging techniques.

• The automotive industry will adopt a chip-based, low cost solid state LiDAR sensor technology instead of large, expensive, mechanical LiDAR systems in the future.

• For the most advanced chip-based LiDAR systems, InP will play an important role and will enable autonomous driving. (Report: Blistering Growth for Automotive Lidar, Stewart Wills). The longer eye safe wavelength is also more appropriate dealing with real world conditions like dust, fog and rain.
