Facet Coating
Helia’s core business is the application of custom-designed coatings for semiconductor facets, including world-leading high-damage threshold designs.
- 20+ years expertise on coatings for diode lasers, SLEDs,
LEDs, optical modulators, photonics integrated circuits,
detectors, etc. - Well-proven processes for all common optical
semiconductor types (Si, GaAs, InP, GaN, GaSb, GaP …) - From large PICs and mm-sized bars down to bars of
150µm cavity lengths - Coatings from the XUV to 25µm in the IR
- A constant commitment to R&D and working with
customers to overcome technical barriers
