How it works
Three lasers, one circular white beam output
Neptune grows single-mode red, green and blue sources directly on the chip, then merges them through integrated, factory-aligned optics into one symmetric RGB beam — no discrete modules to align.
01 · Grow RGB on chip
Single-mode red, green and blue laser sources are grown directly on one chip.
02 · Combine & align
Integrated, factory-aligned optics merge the three colours — no discrete modules to align.
03 · One circular beam
The result is a single symmetric RGB beam, ready to couple into scanning or waveguide optics.

FAQ
Frequently asked questions
A fully integrated photonic chip that combines red, green and blue laser sources — and the optics that combine them — into a single miniature RGB light engine for scanning AR displays.
Neptune is our pointer luminator for laser-beam-scanning (LBS-Holo) displays and is sampling today. Luna is an area luminator for LCoS-class full-field projection, arriving in the second half of 2026.
Single-mode red, green and blue at 450 / 520 / 640 nm, with typical optical output of 15–25 mW per channel.
The Neptune package measures just 4 × 4.5 × 1.5 mm, including a protective cap over the laser diodes and wire bonds.
Integrated optics reduce losses dramatically — a potential 20× improvement in efficiency versus conventional LCoS architectures.
Yes. The platform is built on wafer-scale semiconductor processes, so quality and cost scale the same way they do for chips.
−10 °C to 70 °C, with an on-chip NTC sensor for precise thermal monitoring and stable output.
