Exhibit 99.1
LightSolver to Unveil the First Public Demonstration
of its All-Optical Computer at SC26
LightSolver to present its Boeing corrosion-simulation
work and join Birds of a Feather (BoF) session
on analog computing at the supercomputing conference in Chicago
Rehovot, Israel, November 11, 2026 -- CollPlant
Biotechnologies Ltd. (Nasdaq: CLGN) today announced that its subsidiary LightSolver Ltd. (“LightSolver”), a pioneer of pure
photonic computing and developer of the Laser Processing Unit (LPU)™, will unveil the LPU capabilities in a first public demonstration
at SC26, the International Conference for High Performance Computing, taking place November 15-20, 2026 in Chicago. The demonstration
will be presented at LightSolver’s booth #5102 during the exhibition, November 16-19.
The LPU is a photonic computer designed to process
and solve mathematical problems using light itself, through interacting laser beams, rather than conventional electronic computation.
In this first public demonstration of an all-optical computer, LightSolver will showcase live how the LPU solves real mathematical and
computational problems – including systems of linear equations, differential equations, and complex optimization problems –
using only interacting light.
The LPU is designed to operate alongside conventional
GPUs, with the potential to significantly accelerate certain computationally intensive workloads while offering the potential for reductions
in energy consumption. These capabilities build on previously published, peer-reviewed research conducted in collaboration with the High-Performance
Computing Center Stuttgart (HLRS), as well as ongoing paid collaboration programs with leading industrial partners, including Boeing and
others.
Boeing Corrosion Simulation at the Exhibitor
Forum
LightSolver will present its work with Boeing
on PDE-based corrosion simulation at the SC26 Exhibitor Forum. The presentation will set out the engineering problem and present comparative
benchmark results against existing solvers. The work is part of a paid, multi-year development program with Boeing, announced in April
2026.
Analog Computing with the HPC Research Community
LightSolver will also take part in a Birds of
a Feather session informed by the U.S. Department of Energy report “Analog Computing for Science: From Emerging Technologies to
a Shared Research Agenda,” alongside researchers from HLRS, Pacific Northwest National Laboratory (PNNL), TU Dresden and other institutions.
Dr. Talya Vaknin, Head of Research at LightSolver, will present the company’s perspective on the advantages of keeping most of the
computation in the optical domain.
“The first public demonstration of an entirely
new type of computer — one that uses light itself to perform computation — marks a major milestone for LightSolver as we work
to move from a working prototype toward a commercial product,” said Dr. Ruti Ben Shlomi, Co-Founder and CEO of LightSolver. “It
is an exciting moment for our company and everyone involved in building this new computing paradigm. We see this as an important step
toward our long-term vision of photonic computing in data centers, which we believe has the potential to perform computational workloads
at significantly higher speeds while reducing energy consumption. And there is no better place to showcase this technology than at a leading
supercomputing event, where the world’s experts, researchers, industry leaders, and innovators in high-performance computing come
together. It is the ideal stage to introduce this new computing paradigm to the community that will help shape the future of computing.
We believe that computing with light has the potential to fundamentally transform the future of computing infrastructure.”
