- PolyBoard: Optochips for telecom, datacom and sensing
PolyBoard is HHI's platform for the hybrid integration of passive planar polymer waveguides, active InP components and thin-film filters for polarization and wavelength handling. It enables the quick and cost-efficient development of optochips. These include, among many others, ONUs and OLTs for WDM-PON, coherent receivers for access and AWGs for structurual health monitoring with FBG networks.
- Terahertz sensing: contact free thickness measurement of multilayer structures
THz is an ideal tool for the analysis of multilayer structures, since many materials are transparent at THz frequencies. The advantage of our optoelectronic approach for HHI's novel continuous-wave THz system is the bandwidth of more than 3 THz. This allows the unambiguous determination of material thicknesses over a range of several meters with micron precision.
