Problem
Many photonic applications in the visible and ultraviolet spectrum require compact, high-performance light sources and low-loss waveguide components, but existing solutions are often bulky, expensive, and suffer from high propagation losses, limiting integration in advanced sensing, communication, and quantum systems.
Solution
Brightlight Photonics addresses this gap by offering custom on-chip laser and amplifier modules based on titanium‑doped thin‑film sapphire, delivering widely tunable output (>200 nm range) and single‑frequency operation with narrow linewidths (<5 kHz) and output powers exceeding 10 mW. The platform also provides high‑gain amplifiers (>100 mW) and frequency‑doubled lasers for applications needing shorter wavelengths. In parallel, the company supplies ultra‑low‑loss waveguide devices for the UV and visible bands, including reference cavities, interferometers, and bespoke photonic circuits, achieving propagation losses below 1 dB/m at 780 nm. These integrated photonic components enable compact, high‑precision systems without the need for external bulk optics.
Target Audience
