Company History

Brolis Sensor Technology is a dedicated sensor technology company within Brolis Group, spun-out as a separate entity from Brolis Semiconductors UAB since 2018.  

Brolis Semiconductors was established in 2011 by three Vizbaras brothers – Augustinas, Kristijonas and Dominykas as a spin-off from elite German Walter Schottky Institute. In 2012 the company attracted initial VC funding and built it’s state-of-the-art facility in Vilnius,Lithuania. In 2015 Brolis attracted new investments from major solid-state manufacturers to replace the VC fund and strengthen company’s goal to become a vertically integrated manufacturer. Buy-out of shares from LitCapital was successfully completed in 2017.

Brolis Semiconductors focuses on creation some of the world’s finest infrared laser products from near infrared to mid infrared. With the help of company’s international positioning and state-of-the-art infrastructure, top talent engineering and scientific staff company is able to develop most cutting-edge solutions for security, medical, research and industrial applications. Our unique skill set and world’s largest epitaxy facility for long wavelength infrared optoelectronics has helped to demonstrate numerous world-record performance devices on the largest industrial GaSb substrate platform in the market today.

Since foundation, Brolis Semiconductors has been growing dynamically, marked by numerous awards, continuous innovation and consistent growth in both personnel and infrastructure. Currently Brolis acts across three locations with headquarters and production facility in Vilnius, Lithuania, E-O systems for defense and security sales location in Larne, Northern Ireland, UK and Silicon Photonics activity in Ghent, Belgium. In the end of 2018, Brolis Semiconductors separated the semiconductor and sensor technology into a separate entity – Brolis Sensor Technology UAB. 

BROLIS is a vertically integrated company where all technology layers are in-house: material synthesis by molecular beam epitaxy, III-V processing of lasers and photodetectors, advanced backend technology, hybrid III-V/Si integration, micro-optics and fiber coupling, hermetic packaging, electronics, data science and application development, etc. We are a hardcore hardware-hard technology company with our own path towards revolutionizing the markets.

Brolis Sensor Technology operates in two European locations

Brolis Sensor Technology BV a dedicated R&D office for silicon photonics and III-V frontend technology in Ghent, Belgium.

Brolis Sensor Technology UAB HQ, R&D and production for III-V design, epitaxy, backend, integration, system and application development and productization. 


Get to know us


Brolis is not a typical young technology company. It does not fit any “Silicon Valley” template and is not a company of vice presidents and advisors. Brolis is a family-owned, profitable hardware-hard company of engineers and scientists. A team of difficult-to-pronounce names and strange accents – we create technology that never existed before.

Know-how and IP

Brolis’ know-how encompasses 10 years of experience in antimonide-based material science, device design and silicon photonics integrated circuit engineering. Thousands of experiments and simulations have allowed us to build a unique database of material parameters, device design rules, fabrication processes and patents.
