Polymer fiber-optic electric field sensors were designed and fabricated,using polymer BPAN-NT material as the active core layer.Assuming that the electro-optic coefficient r13 of the core polymer is 10 pm/V,electric field sensors were designed with half-wave electric fields of 36.2 kV/m and 15.8 kV/m,respectively.The optical ridge waveguide was fabricated by reactive ion etching(RIE),the active polymer core was poled by corona,and the dipole antenna electrode was processed by sputtering and lithography.The ...
