    Abstract: Provided is a tunable external cavity laser diode using a variable optical deflector wherein the variable optical deflector, in which a refractive index varies according to an electrical signal, is arranged in a triangular shape between a concave diffraction grating and a reflective mirror. Since a resonant frequency is changed using the electrical signal rather than the mechanical movement, the stable operation and continuous high-speed tenability may be enabled. In addition, when the tunable external cavity laser diode according to the present invention is implemented in an InP/InGaAsP/InP slab waveguide, a variable time determined by the carrier lifetime may be reduced to several nanoseconds or less, the miniaturization is enabled, and the manufacturing costs are significantly reduced due to the process simplification. Moreover, when the concave diffraction grating is designed based on a silica (or polymer) based slab waveguide, the fabrication may be performed even by a lithography process having low resolution, thereby enhancing reproducibility and uniformity of the diffraction grating, and accordingly reducing the manufacturing costs.

    Abstract: The present invention relates to all-optical OR and XOR logic elements employing saturable absorbers as optical gates. Saturable absorbers are arranged in paths of the Mach-Zehnder interferometer, respectively. If the total power of an input optical signal and a continuous wave signal is higher than a transparent input power of the saturable absorbers, the input optical signal passes through the saturable absorbers, and then the optical signals through the two paths are combined, so that it is possible to obtain the operational characteristics of the OR and XOR logic elements. According to the present invention, unlike the optical logic element using a cross-phase modulation by a semiconductor optical amplifier, phase difference depending upon the input optical power is not generated between two paths, so that it is possible to alleviate a restriction of an allowable range of the input optical power.

    Abstract: Provided is an apparatus for improving the sharpness of an image. The apparatus includes an edge detector, an effective edge judging unit, an effective edge classifying unit, an isolated edge judging unit, and a 2-D HPF applying unit. The edge detector calculates an edge value using brightness relation with neighboring pixels with respect to each of pixels of an input image. The effective edge judging unit determines effective edge pixels. The effective edge classifying unit determines weak edge pixels and strong edge pixels. The isolated edge judging unit judges an isolated edge pixel included in an isolated edge. The 2-D HPF applying unit applies a first 2-D HPF to the weak edge pixels, and applies a second 2-D HPF to the strong edge pixels to generate edge strengthening values. The edge strengthening value applying unit adds the edge strengthening values to brightness values of the respective pixels of the input image.

    Abstract: A continuously variable transmission comprises a drive shaft which has first and second drive shafts and is provided with rotational power, a planetary gear unit which is meshed with the first drive gear of the drive shaft and has a sun gear secured to an output shaft, and a transmission which receives a portion of driving force to provide additional output. Interruption of power transmission when shifting is prevented. Also, since the construction of the continuously variable transmission is simplified to minimize the load generated due to a shifting operation, power loss resulting from shifting is reduced, and the manufacturing cost is decreased. In particular, since vibration and noise generated upon shifting are decreased, the continuously variable transmission can be widely applied, from a small power device such as a bicycle or a motorcycle to a large power transmission apparatus such as an industrial machine.
