摘要： 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. In this case, the total reflection type optical switch is capable of high speed switching, and is not limited to usages of an optical switch, and may be used as a variable optical attenuator by adjusting the voltage and current being applied. According to the present invention, it is possible to use the difference of the refraction indexes of the silica optical waveguides and the polymer due to temperature changes to transilluminate or totally reflect an optical signal according to changes of the refraction index of the polymer, thereby improving loss characteristics of the optical signal.

摘要： Provided is a wavelength division multiplexer/demultiplexer having a flat wavelength response. In the wavelength division multiplexer/demultiplexer, a modified taper-shaped optical waveguide is interposed between an input waveguide and a first slab waveguide, such that the distribution of an optical signal input to an Arrayed Waveguide Grating (AWG) has a sinc-function shape. Thus, a flat wavelength response can be obtained in an output waveguide. In addition, the modified taper-shaped optical waveguide interposed to obtain a flat wavelength response has a small size and a simple structure, and thus can be applied to a conventional wavelength division multiplexer/demultiplexer without a design change.

摘要： An optical waveguide platform and a manufacturing method thereof are provided. In the provided optical waveguide platform, a terrace on which an optical device is mounted is formed by using an etch stopper pattern formed on a lower clad layer. Therefore, the optical device is mounted without processing a silicon substrate. In addition, in the provided optical waveguide platform, the etch stopper pattern is formed on the lower clad layer to prevent defocus in a photolithography process due to an etch step, so as not to damage a fine waveguide pattern. Moreover, an optical waveguide is formed on the terrace in manufacturing the optical waveguide platform to examine the characteristics of the optical waveguide device before etching a trench.
