Patent number: 9207403Abstract: The present invention relates to a total reflection type optical switch using polymer insertion type silica optical waveguides and a manufacturing method thereof. The total reflection type optical switch forms a trench in an intersecting point of the silica optical waveguides having two optic routes, and inserts a polymer into the trench. A total reflection type optical switch has a heater which heats the polymer. The polymer is made of thermo-optic material, and totally reflects an optical signal as a refraction index falls when heated by the heater. In addition, when not heated by the heater, the polymer transilluminates the optical signal. When the polymer is made of electric-optic material, the total reflection type optical switch may have upper and lower electrodes for applying an electric field in the polymer instead of the heater.Type: GrantFiled: October 25, 2011Date of Patent: December 8, 2015Assignee: Photonics Planar Integration Technology, Inc.Inventors: Young Sic Kim, Jang-Uk Shin, Hyung-Myung Moon, Jin-Bong Kim
