Abstract: PURPOSE: A method for fabricating a progressive wave coplanar electrode of a high speed polymer mach-gender optical modulator is to simplify a design of an electrode and reduce a DC-drift and an operating voltage. CONSTITUTION: A high speed polymer optical modulator having a progressive wave coplanar electrode comprises a channel light guide(1), a progressive coplanar electrode(3), an incline plane(2) and an input/output unit. The progressive wave coplanar electrode is formed by etching the channel light guide in order to increase an overlap constant of an electric field and a guide mode. The coplanar electrodes(6,9) are crossed over the incline plane. The input/output unit inputs/outputs a microwave through a coupler having a coplanar structure. The light guide is implemented with a mach-gender interferometer. A mode of the light guide is identical to that of an optical fiber.

Abstract: PURPOSE: An electric optical polymer for a wavelength division multiplexing optical communication network, a high speed tunable selecting filter using multi-grating and their operating method are provided to enable implementation of a dense wavelength division multiplexing based optical communication and be used for an optical information storing device technique utilizing an optical refraction. CONSTITUTION: An optical waveguide(103) collects a plurality of lights made incident to a single mode. A Bragg grating unit passes only a light of a desired wavelength among the plurality of lights made incident along the optical waveguide(103) and reflects the remaining lights along the optical waveguide(103) to emit them externally. A proceeding waveform electrode(105) changes a region of a Bragg grating reflection wave by an electro-optical effect and transmits or reflects a specific wavelength selectively. A TEC(106) tunes the wavelength of the whole bragg reflection wave by using a heat optical effect of a polymer.
