摘要： A gas discharge image display is formed by disposing a plurality of fluorescent lamps 1 each comprising a glass bulb 2 within which a rare gas is sealed, one or more pairs of external electrodes 5a and 5b located on the outer wall of the glass bulb 2, and a fluorescent layer 3 formed on the inner wall of the container facing the external electrodes 5a and 5b. An alternating voltage pulse is applied between the paired external electrodes 5a and 5b by an X drive circuit 9 and a Y drive circuit 10 for discharge light emission, thereby displaying an image. The pressure and alternating voltage in the fluorescent lamp 1 are changed in response to the type of fluorescent material, thereby making near light emission and discharge characteristics of the discharge lamps which differ in electric characteristics.

摘要： A variable dispersion compensator includes an optical waveguide, a temperature controller. The optical waveguide has a chirped grating having a Bragg wavelength changing along the longitudinal direction of the grating. A temperature distribution T1(x) is applied to a central portion of the grating, defined as a region where a distance x from an end of the grating is a range of 20 % to 80 % of total length of the grating. Temperature distribution T2(x) and T3(x) are applied to end portions of the grating, defined as two regions extending from respective ends of the grating to the central region, respectively. At least one of T2(x) and T3(x) has a distance dependence different from that of the T1(x).

摘要： A method of manufacturing a grating in an optical waveguide that includes a core and a cladding covering the core. The method includes scanning a laser beam along an optical axis of the optical waveguide to modulate the refractive index of the core. The core is made of a material having a refractive index that is changeable upon irradiation by radiation. In addition, in scanning the core, the irradiation range of the laser beam is controlled and the core is scanned several times. Therefore, a predetermined distribution of irradiation is obtained in a direction of the optical axis of the grating.

摘要： A polarization dispersion compensation apparatus includes a polarization controller, a polarization beam splitter, an optical delay circuit, and a polarization beam combiner. The polarization controller controls polarization of an optical signal so that the polarization axis of the input optical signal substantially coincides with the optical axis of an optical transmission line, and the polarization beam splitter section splits the optical signal into two polarized components perpendicular to each other. The optical delay circuit section causes a difference in delay between the two polarized components, and the polarization beam combiner section combines the two polarized components output from the optical delay circuit section. Each of the polarization beam splitter section and the polarization beam combiner section includes a symmetric Mach-Zehnder interferometer having optical transmission lines in two arms, each arm including a temperature control and a birefringence portion for compensating polarization dispersion between the two polarized components.
