Helia Photonics: the ultimate innovators in thin film optical coatings

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
