Optical coatings on semiconductor devices is our main business for one reason: we excel at it. We use custom designed and fabricated jigs and holders to delicately handle your devices and avoid any damage. In the majority of cases, multiple bars can be loaded simultaneously to make the coating process more time and cost-effective.
We are capable of performing semiconductor wafer-level, bar-level and chip-level coatings to suit your needs on a range of substrates. We offer coatings on GaAs, GaN, GaSb, InP and Si, as well as processes specifically designed for AlGaAs lasers. We can deposit coatings to perform anywhere in the 0.4-18µm range.
Helia specialise in tackling challenging coating requirements. We produce coatings with high laser damage thresholds, and are experienced in coating high power semiconductor pump lasers and arrays, which require high Catastrophic Optical Mirror Damage (COMD) thresholds.
