Zinc telluride can be easily doped, and for this reason it is one of the more common semiconducting materials used in optoelectronics. In Semiconductor production doping is the process of intentionally introducing impurities into an extremely pure (also referred to as intrinsic) semiconductor to A semiconductor' is a Solid material that has Electrical conductivity in between a conductor and an insulator; it can vary over that Optoelectronics is the study and application of electronic devices that source detect and control Light, usually considered a sub-field of Photonics.
Vanadium-doped zinc telluride, "ZnTe:V," is a non-linear optical photorefractive material of possible use in the protection of sensors at visible wavelengths. Vanadium (vəˈneɪdiəm is a Chemical element that has the symbol V and Atomic number 23 The photorefractive effect is a nonlinear optical effect seen in certain Crystals and other materials that respond to Light by altering their ZnTe:V optical limiters are light and compact, without complicated optics of conventional limiters. ZnTe:V can block a high-intensity jamming beam from a laser dazzler, while still passing the lower-intensity image of the observed scene. A dazzler is a type of a Directed-energy weapon employing intense visible light usually generated by a Laser ( laser dazzler) It can also be used in holographic interferometry, in reconfigurable optical interconnections, and in laser optical phase conjugation devices. Holography (from the Greek, ὅλος - hólos whole + γραφή - grafē writing drawing is a technique that allows the Interferometry is the technique of using the pattern of Interference created by the superposition of two or more Waves to diagnose the properties of In Telecommunications interconnection is the physical linking of a carrier 's network with equipment or facilities not belonging to that network Nonlinear optics (NLO is the branch of Optics that describes the behaviour of Light in nonlinear media, that is media in which the dielectric polarization It offers superior photorefractive performance at wavelengths between 600-1300 nm, in comparison with other III-V and II-VI compound semiconductors.
