Patent ID: 8837952

Claim:
A textile-structure optical communication interface device comprising: a diffusing unit configured to diffuse an optical signal including information transmitted between information devices; and a condensing unit configured to condense the optical signal, wherein the diffusing unit includes: yarns, optical fibers woven with the yarns; grooves configured to allow the optical signal to be diffused in the optical fiber via an outward diffusion path and configured to allow the optical signal to be incident upon the optical fiber and to be condensed via a condensation path, the optical signal being input via an inward input path, wherein the grooves are formed on the upper inner surface of the optical fiber in a predetermined pattern, wherein the optical signal is input into an input path at an end of the optical fiber and is reflected on the inner surface of the optical fiber based on a total reflection principle to be diffused via the grooves, wherein the optical signal is input into an inward input path of the optical fiber and is incident upon the inner surface of the optical fiber to be condensed via a condensation path at one end of the optical fiber.
