5G-Band Antenna-Coupled Electrode Electro-Optic Modulator for Discriminating Two Orthogonal Polarization Components of Wireless Signal

5G-band antenna-coupled electrode electro-optic modulators for detecting and discriminating two orthogonal polarization components of wireless signals are designed and fabricated. Good operation characteristics as an electro-optic sensor for the 5G-band with orthogonal polarization discrimination were verified experimentally. In addition, up-to 5 Gb/s ASK wireless signal detection in the 28 GHz band was experimentally demonstrated. This devise is suitable for applications to ~10 Gb/s wireless communication and precise antenna measurement for 5G mobile systems.
