We offer GaN-based MMIC processes for customized circuit designs in several frequency bands. Contact Dr. Oliver Hilt Phone +49 30 63922791 Email oliver.hilt@fbh-berlin.de X- and Ka-band…
Passivation & Coating of Laser Facets
/en/transfer-services/services/processes/laser-facet-passivation-coating
We passivate GaAs laser facets using our patented process. This enables both a high output power and a high long-term stability of the lasers. After the passivation process we additionally…
Qualification of Epitaxial Layers
/en/transfer-services/services/processes/epitaxial-layer-qualification
We qualify epitaxial layers using a stable device process. It is well known that non-destructive material investigations as usually applied for epixial wafer characterization may not be able to…
