A reflected light wavelength scanning device having a silicon photonics interrogator is provided. The device includes: a light source module for outputting broadband light; an optical sensor that receives light output from the light source module through a circulator, reflects light in a specific band to the circulator, and transmits light in a band other than the specific band; and an interrogator for selectively injecting the polarized light by separating the polarized light from the reflected light input through the circulator.

The present disclosure relates to a polarity detector for detecting polarity of a patch cord, that is capable of sequentially inputting an optical signal into channels of a connector of the patch cord, receiving the optical signal being output, and thereby discerning the polarity of the patch cord quickly and precisely. Particularly, the present disclosure is characterized to spectrally output the optical signal from the light source as a plurality of unit optical signals, and to selectively block or pass the spectrally output plurality of unit optical signals, by heat, and thereby effectively inputting the optical signal into each channel of the connector.

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.
