History & Mission


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 acitvity in Ghent, Belgium.

Project description

SWIRsense focuses on the development of novel compact and cheap tunable laser in the short-wavelength
infrared spectral region (SWIR) based on direct interband transition in GaSb quantum wells for spectroscopy and
sensing. We will deliver a small-footprint low-power consumption laser module comprising advanced
semiconductor gain chip and external cavity opto-mechanical system with 100 nm tuning bandwith around 2.2
micron center wavelength with up to 5 mW CW output power for sensing applications such as biomedical sensing of liquid substances ( metabolites, blood analytes, etc.).
