Helia Photonics Ltd

About

Helia Photonics specialises in demanding optical coatings for micro-optics and light emitting semiconductor devices. With over 15 years of trading and over a hundred well established customers, Helia Photonics aims to become the premier player in its field.

Helia employs a range of vacuum optical coating technologies and with a keen interest in reinvestment and research, plans to ensure a strong foothold at the forefront of high power diode lasers and high performance antireflection coatings.

Helia are constantly looking at global developments in photonics devices & ensuring that processes are in place to address these ever-demanding requirements.

Active areas of internal research & development include:

- Lifetime enhancing antireflection (AR) coatings for GaN lasers
- Lifetime enhancing OC coatings for AlGaAs lasers
- Ultra-broadband antireflection (AR) coatings for long wave infrared quantum cascade lasers (LWIR QCLs)
- Tight-edge dichroics for Silicon detectors
- Ion Beam Sputtering (IBS) & Atomic Layer Deposition (ALD) for photonics devices
- Low energy deposition for organic devices

Helia Photonics are active in development & research with organisations such as the Technology Strategy Board (TSB), The Scottish University Physics Alliance (SUPA) & the Small Companies Innovation Scheme.

- High damage threshold coatings for high power semiconductor pump lasers & arrays
- Novel high catastrophic optical mirror damage (COMD) threshold processes for AlGaAs lasers
- Ultra-low anti-reflection coatings for semiconductor laser facets & free space optics (FSO)
- Infrared anti reflection (AR)/ high reflectivity (HR) coatings for Quatum Cascade Lasers (QCL)
