=== Optical Communications ===
InP is used in lasers, sensitive photodetectors and modulators in the wavelength window typically used for telecommunications, i.e., 1550&nbsp;nm wavelengths, as it is a direct bandgap III-V compound semiconductor material. The wavelength between about 1510&nbsp;nm and 1600&nbsp;nm has the lowest attenuation available on optical fibre (about 0.2&nbsp;dB/km).<ref>{{Cite journal |last1=D’Agostino |first1=Domenico |last2=Carnicella |first2=Giuseppe |last3=Ciminelli |first3=Caterina |last4=Thijs |first4=Peter |last5=Veldhoven |first5=Petrus J. |last6=Ambrosius |first6=Huub |last7=Smit |first7=Meint |date=2015-09-21 |title=Low-loss passive waveguides in a generic InP foundry process via local diffusion of zinc|journal=Optics Express |volume=23 |issue=19 |pages=25143–25157 |doi=10.1364/OE.23.025143 |pmid=26406713 |doi-access=free |bibcode=2015OExpr..2325143D }}</ref> Further, O-band and C-band wavelengths supported by InP facilitate [[Single-mode optical fiber|single-mode operation]], reducing effects of [[Modal dispersion|intermodal dispersion]].
