Abstract

The invention discloses a multi-pin corona polarization field structure of a PMMA (Polymethyl Methacrylate) / DR1 (Disperse Red 1) polymer modified film, relates to the multi-pin corona polarization field structure and provides the multi-pin corona polarization field structure of the PMMA / DR1 polymer modified film, which can reduce a polarization voltage while homogenizing the corona polarization field and improve the polarization efficiency under the circumstance of invariable polarization voltage. The structure is provided with four pin electrodes; the circumferential two pin electrodes are symmetrically arranged at the edge and the two pin electrodes at an inner layer are symmetrically arranged at two sides of the center; the distance between the circumferential pin electrodes and the pin electrodes at the inner layer is 10-12 mm, the electrode voltage in a polarization field is 3-4 kV, the bottom electrode on a film is grounded and the electric potential is 0 V; the distance a between the pin electrodes and the bottom electrode is 10 mm generally used in the traditional corona polarization, and the ratio of a to the size b of the bottom electrode is 1:3-1:4.

Description

technical field [0001] The invention relates to a multi-needle corona polarization field structure, in particular to a four-needle evenly distributed corona polarization field structure for PMMA / DR1 polymer modified film. Background technique [0002] With the development of waveguide preparation technology and semiconductor laser technology, and driven by emerging technologies such as optical communication and optical computer, research on nonlinear optical properties in dielectric waveguides has received more and more attention. Considerable progress has been made on both fronts. Among them, polarized polymer materials have the characteristics of high nonlinear coefficient, low permittivity, easy processing, and compatibility with existing integration processes, so they have broad application prospects in the field of integrated optics, especially optical communication devices. Polarized polymers use the polymer skeleton as the carrier of nonlinear optical molecules. Unde...
