Antenna-coupled electrode electro-optic (EO) modulators operating in the 28-GHz band were analyzed, designed and fabricated for the applications to the next generation (5G) mobile wireless communication systems and to the precise antenna measurement systems. By analyzing the antenna-coupled electrode in detail with the 3-D model of the EO-crystal-stacked substrate, the electric field enhancement factor of approximately 8000 times of the irradiated 28-GHz field can be obtained for the optical modulation, which enables us to have a compact wireless-optical signal converter without external power supply. The designed EO modulator was fabricated using a 50-µm-thick LiNbO3 crystal film and a 250-µm-thick SiO2 base substrate, its signal conversion characteristic from the 28-GHz band wireless to optical signals were demonstrated successfully in the experiment. |
