Fabrication of free-standing films of poled EO polymers and laminated films for ultra-high-frequency electric field detection

Ultra-high frequency electric field detection such as terahertz electric field is one of the most important terahertz technologies, and various applications are expected in fields of terahertz science and ultra-high-speed wireless communication. In this research, we have developed a new fabrication technique for producing free-standing films of poled EO polymers and laminated films with various film thicknesses for a high-efficiency and wideband THz wave detection using Pockels effect or Stark effect of EO polymers. For this purpose, polycarbonate (PC) based EO polymers with a high glass transition temperature and robustness are used.
