摘要： An optical image stabilizer for a camera lens assembly is disclosed and includes: a board having an image sensor on one surface thereof; a double actuator disposed at one side of the board for moving the board in a first direction and a second direction perpendicular to the first direction on a plane; and a guide means for guiding the movements of the board in the first and the second directions, while preventing the board from rotating about an optical axis of the camera lens assembly. The double actuator for moving the board in two directions is disposed at only one side of the board, so that the camera lens assembly including the optical image stabilizer can be downsized. Further, the guide means permits the board to move only linearly in the first direction and the second direction, thereby preventing the image sensor from rotating around an optical axis and thus improving the reliability of the camera lens assembly.

摘要： An optical demultiplexer having at least one Bragg diffraction grating for minimizing crosstalk on the sides of transmitting and receiving optical signals, as well as an optical communication module using the optical demultiplexer. The optical demultiplexer has first and second waveguides arranged adjacent each other in a predetermined section in order to perform mode coupling, so that the optical signals input through one end of the first waveguide are transmitted to a light receiving element through the second waveguide, and in which output light waves inputted through the other end of the first waveguide are output through the one end of the first waveguide. A first Bragg diffraction grating is formed on the second waveguide and haa wavelength selectivity, for minimizing crosstalk by transmitting a reception wavelength of the optical signals at about 100% and by reflecting a wavelength of the output light waves at about 100%.
