Be the First to Experience & Test – Pre‑Launch Access
Featured Products
Be among the first to test our cutting-edge technologies—currently in pre-launch—and explore how they can elevate your sensing or communications applications. Ready to see what these innovations could do for your system?

Fused Fiber Bundle
They consist in precise, customizable N‑fiber geometries, perfect for applications requiring multichannel light delivery or sensing accuracy. Used for remote environment monitoring, long-range sensing, quantum, or biomedical detection.

Photonic Lantern
Our newly developed photonic lanterns (2‑ and 3‑mode variants at 850, 1300, and 1550 nm) offer high isolation (<0.2 dB insertion loss, >28 dB mode separation) and compact packaging—ideal for boosting SNR in coherent detection, LiDAR, and space communication systems. Add your voice to the pre‑launch feedback loop.
