Satellites are transmitting more data than ever before, increasing the need for faster, secure and reliable communication between space and Earth. To meet this demand, U of T startup TightBeam Photonics is developing a new generation of optical ground stations that use laser-based communications in place of traditional radio systems.
The company’s optical ground stations use photonic chips, which manipulate light to carry information. Unlike conventional radio-based systems, laser communications can transmit large volumes of data at high speeds. TightBeam is building this technology into ground stations that are smaller, more portable and less expensive, with the potential to make advanced satellite communications more accessible.
The benefit of this technology extends beyond commercial space operations to national defence. Secure satellite links are important for transmitting sensitive information, while faster data transfer can help make better use of the number of satellites in orbit. Laser-based systems also offer greater protection from interference than traditional radio communications.
That potential has already attracted international attention. In 2025, TightBeam was selected for the 2026 cohort of the NATO Defence Innovation Accelerator for the North Atlantic (DIANA), a program that helps companies develop technologies to address defence and security challenges. Through NATO DIANA, TightBeam gains access to funding, testing facilities, technical experts and defence end users to help advance its technology toward deployment.
While the company is gaining recognition internationally, its growth has been closely tied to the University of Toronto innovation ecosystem. TightBeam worked with U of T’s Innovations & Partnerships Office in its early stages and has received support from University of Toronto Early-Stage Technology (UTEST), the university’s deep-tech startup accelerator. Co-founder and CEO Mark Barnet serves as Mechanical Systems Engineering Lead at U of T’s Dunlap Institute for Astronomy & Astrophysics and Systems Engineer Robin Swanson is a postdoctoral fellow and former U of T PhD student. Collectively, the leadership team brings expertise in astronomy, optics, satellite systems and photonics. In 2026, TightBeam Photonics was recognized with the Desjardins Startup Prize for its progress in commercializing advanced communications technology. Past recipients of the prize have gone on to raise tens of millions of dollars in funding.
Building sovereign space capabilities requires more than access to orbit. It also depends on secure, reliable communications infrastructure. Through its work in optical communications, TightBeam Photonics is developing technology with the potential to support Canada’s next generation of space capabilities.
