Inventor: NISHIMURA MICHIYO
IPC: H01S5/50
Filed: 1991-05-07
Abstract: PURPOSE:To solve polarization dependency without deteriorating other characteristics. CONSTITUTION:This optical amplifier device is provided with a polarization selective light loss part 1 which applies a light loss at a prescribed ratio to the polarization component for the purpose of compensating the polarization dependency of the amplification rate between input and output light rays 4 and 5 together with an optical amplifying section 2 which applies a gain to the input light 4 from the outside so as to compensate the difference in the amplification degree by the polarized light as a whole. This polarization independent type optical amplifier device solves the polarization dependency without deteriorating the other characteristics exclusive of the amplification characteristic, such as noise characteristic and is, therefore, adequately used for optical communication systems, networks, etc. Since external optical parts, etc., are not so much used, this device is suitable for constitution as a module and is adequately incorporated into an integrated optical anode as well.

Abstract: PURPOSE:To make the space between the liquid crystal devices inconspicuous, in case that plural numbers of the liquid crystal devices are arranged so as to constitute a large screen by mounting slightly larger light transparent films than the display area of liquid crystal pannels on the monitoring side of the liquid crystal display device, respectively. CONSTITUTION:The large screen is constituted by arranging the devices A1, A2, A3... in the longitudinal and lateral directions. The light transparent films 5 are provided on the devices by sticking the films on the devices so as to project slightly over the external sizes B1, B2, B3... of the liquid crystal pannels 3 and the color filters 4, respectively.
