Abstract
The value of electro-optic coefficient r33 of an electro-optic (EO) polymer film depends on the polarization density achieved after the electric poling process. In this letter, we report a high temperature liquid contact poling method which provides a poling field as high as 250 V/μm in LD-3 EO polymer film with less surface damages. The r33 value was measured to be 18 pm/V at 633 nm which is 40°/V higher than the previous reported datum. Such a high poling field and therefore larger r33 value are not achievable through either contact poling or corona poling.Keywords
