We excel at creating epitaxial structures tailored to match specific needs, helping our clients gain and maintain a competitive edge. Offering technological solutions that exceed current limits of knowledge, we have succeeded in developing unparalled epi-structures for lasers, transistors and photodetectors, creating new quality benchmarks.

ENT is VIGO System’s Epitaxy Division that produces high-grade III-V compound semiconductor epitaxial structures for photonic devices (F-P, VCSEL, QCL lasers, photodetectors), microelectronic devices (diodes, transistors) and others. We focus on highly innovative products for wireless, TC, sensing, or printing applications.

VIGO System is the world’s leading manufacturer of standard and customized high-tech uncooled photodetectors of middle and long wavelength range for security, military technology, industrial, space, medical, transport and environmental protection applications.

What We Do

We create atomically engineered epitaxial layers of binary, ternary, quaternary and quinary III-V compound semiconductor by MOCVD epitaxy, which is the deposition of thin crystalline films (1nm to several micrometers) on GaAs or InP substrates.

Our epi-wafers are characterized by precisely controlled thickness, chemical composition, photonic and electrical properties as well as excellent uniformity and reproducibility, demonstrated with our state-of-the-art measuring tools.


Our holistic approach elevates the technology to create solutions that consistently meet and exceed client expectations.

Wlodek Strupinski, Head of Epitaxy Division

Wlodek has more than 35 years’ experience in III-V semiconductor compounds technology for micro- and opto-electronics, silicon carbide compounds for high-power electronics, graphene and other 2D nanomaterials. He specializes in metal-organic vapor phase epitaxy (MOVPE/MOCVD) of GaAs-, InP-, GaN-related, SiC and graphene.

His research interest includes epi-structures for transistors, microwave diodes, varactors, lasers, photodetectors, waveguides, LEDs, QDs, SOA, etc. He has developed many epitaxial technologies which later were successfully used in the commercial production of epi-wafers and electron devices. He also has expertise in developing and managing projects for government and the EU, such as the Graphene Flagship Project.
