We have proposed and developed new antenna-coupled-electrode (ACE) electro-optic modulators (EOM), which enable us to convert microwave/millimeter-wave wireless signals to optical signals directly without external power supply. The basic operations of the proto-type ACE EO modulators have been demonstrated successfully in the frequency range of 10-60 GHz. Their applications to future 5G wireless communication systems and millimeter-wave radar systems are now undergoing. In this report, the improvement of the conversion efficiency of ACE EOM by use of new fluorine-based resign with low dielectric constant and low loss from Sumitomo Electric Industries is presented. 60 GHz wireless signals of 10 mW were directly converted to optical signals with ~100 mrad modulation index, which is enough for over 1 Gb/s data transfer in wireless links. The analysis of the ACE using fluorine-based resign, the design and fabrication of the ACE EOM, and experimental demonstrations are presented. |
