A display substrate and a display device including the same are provided. The display substrate includes a first substrate which is divided into a display portion including pixel regions and a non-display portion including a region other than the display portion. Color filters are formed in the pixel regions of the substrate to respective thicknesses. At least one stepped pattern is formed on the non-display portion of the substrate and from the same material as used to form at least one of the color filters. The stepped patterns are formed at an area occupancy density of 20% or more of the non-display portion. A minimum distance is maintained between the stepped patterns and the pixel regions.

The present invention relates to a passive wavelength division multiplexing device for automatic wavelength locking and a system thereof including an optical multiplexer, an optical filter, an integrated optical receiver monitor, and a tunable optical transmitter. Through wavelength locking that adjusts a wavelength of an optical signal, which changes according to an external environment such as a temperature change, into a wavelength of an optical signal having the maximum optical intensity, communication quality may be maximized by securing a stable communication channel, a locking time and a communication channel setting time may be reduced, and more robust locking may be guaranteed.

摘要:
A method and an apparatus for manufacturing an optical fiber preform. The method manufactures the optical fiber preform by depositing soot created through a chemical reaction on an inside wall of a reaction tube. The created soot is charged with a first predetermined charge to adhere soot, which is not deposited on the inside wall of the tube, to an electrified body charged with a second predetermined charge opposite to the first predetermined charge. The electrified body is adapted for movement to transport the unused soot to an exterior of the reaction tube. The electrified body is energized with a charge identical to the first predetermined charge of soot, thereby exhausting soot adhering to the electrified body to an exterior of the reaction tube.
