The CORX – Coherent Optical IQ Receiver is a fully integrated, high-performance reception module for coherent optical signals in the C-band. Integrated Coherent Receivers are optical components, which beat an incoming signal against a local oscillator (LO), which is detected with 4 balanced receivers, after appropriate polarization and phase shifts. With bandwidths up to 60 GHz and a built-in tunable laser, it is ideal for analyzing complex modulation formats and the highest symbol rates. Tens of active and passive devices, including high speed waveguide Ge/Si photodetectors, edge couplers, 1×2 power splitters, polarization rotator and beam splitters, 90 degree. The CORX Coherent Optical Receiver is a turn-key instrument designed to interface with any real-time oscilloscope by providing 4 single-ended RF outputs. The 90 degree-hybrid mixes the LO with the signal and. Innovations for the digital society of the future are the focus of research and development work at the Fraunhofer HHI. The institute develops standards for information and communication technologies and creates new applications as an industry partner.
