Sapphire photonics
for a bright future

Brightlight Photonics is headquartered at The Engine Accelerator in Cambridge. We are looking for talented physicists and engineers, especially those with a photonics background, to join us in revolutionizing CMOS-compatible light sources for biomedicine, metrology, and quantum technologies.

Portfolio

Titanium:Sapphire

On-chip lasers and amplifiers made from titanium-doped thin-film sapphire.

  • Widely tunable lasers (tuning range > 200 nm)

  • Single frequency laser arrays (power > 10 mW, linewidth < 5 kHz)

  • Amplifiers (power > 100 mW)

  • Frequency-doubled lasers

Ultra-low-loss UV and visible photonics

We offer custom photonic solutions in the visible and ultraviolet, from bare chips to fiber-interfaced devices.

  • Reference cavities

  • Interferometers

  • Custom R&D circuits

Waveguide propagation losses:

  • 780 nm: < 1 dB/m

  • 400 nm: < 10 dB/m
