Popis: We present a method for producing electrooptic (EO) polymer films with EO coefficients 40−50 pm/V at 785 nm which are suitable for use as emitters and sensors of THz radiation. Direct comparison with ZnTe shows that our EO polymers are more efficient THz emitters than ZnTe. The THz field generated from a 80 μm thick poled polymer film is equal to that generated from a 1 mm thick ZnTe crystal. A model for the THz generation via optical rectification from a poled polymer has been developed and verified experimentally in a THz system using a polymer emitter and a ZnTe sensor.
