Abstract: A first light waveguide is formed, and second and third light waveguides are respectively connected to the first light waveguide at first and second positions. A first coupler for effecting light branching and/or combining is arranged near the first position, and a second coupler for effecting light branching and/or combining is arranged near the second position. An optical amplifier is arranged on the first light waveguide between the first and second positions for compensating for a light loss of a light wave caused by each of the first and second coupler.

Abstract: In a light source apparatus, the polarization mode of oscillation light from a semiconductor laser is switchable between two different polarization modes when a modulation current is injected into a portion of a light waveguide of the semiconductor laser. Light in one polarization mode and light in the other polarization mode are separately obtained from the oscillation light from the semiconductor laser. At least the light in one of the two different polarization modes is converted to an electric signal. Current injected into the semiconductor laser is controlled based on the electric signal such that a modulation state of light from the semiconductor laser is stabilized. The light in the other polarization mode, or light in one polarization mode emitted from the other emission side of the semiconductor laser may be used for optical transmission.

Abstract: PROBLEM TO BE SOLVED: To easily form an electron emitting section on a conductive thin film at a high yield by forming the conductive thin film between a pair of element electrodes arranged on an insulating substrate, and applying droplets from an ink jet injection device to form connecting terminals between the element electrodes and wires. SOLUTION: A pair of electrodes 2, 3, wires 6, 7, and a conductive thin film 4 between both electrodes 2, 3 are formed in sequence on an insulating substrate 1 by vacuum deposition and photolithography. Droplets are applied by an ink jet injection device, and the electrodes 2, 3 and the wires 6, 7 are connected by the precursors of connecting terminals 8a, 8b. A solution dispersed with a metal in water or a solvent is used for the droplets. A system capable of controlled forming and feeding an extremely small quantity of droplets, e.g. a piezo-jet system, is preferably used for the ink jet injection device. The precursors are baked to remove the solvent, and the connecting terminals 8a, 8b are formed. A forming process is applied to form an electron emission section 5 on the thin film 4, and an electron emitting element is obtained.
