“…It is clear that the orientation of nonlinear molecules in bulk samples is very important with respect to the magnitude of the second-order nonlinear properties. However, inactive polymeric systems can be converted into a second-order nonlinear medium by electric field-induced poling process [6,5]. In non-crystalline materials, the anisotropy induced by an external electric field in the polymers could remain as long as the electric field is present, temporarily (relaxation time) after withdrawing the field or settle down permanently.…”

The basic theoretical concepts on which the electro-optic linear effect are based and the optic modulation are briefly described in this work. A novel method for obtaining a doped bulk polymer with electro-optic properties by means of the incorporation of an organic pigment called 2-Methyl-4-Nitroaniline (MNA) in epoxy resin followed by a poling technique of the MNA molecules by means of the application of a strong electric field is proposed. Also, the construction of an optic modulator cell is described showing the experimental arrangement and the results obtained, with the corresponding calculation of their main parameters. A simplified mathematical model is also proposed.

“…It is a highly polarizable yellow pigment, which makes it ideal for obtaining electro-optic materials. In its crystalline state, an electro-optic coeficient up to 500 pm/V has been obtained [6], but unfortunately, the growth process for obtaining bulk crystals is very difficult and expensive [7,8].…”
