Abstract: PROBLEM TO BE SOLVED: To obtain an economical and good efficient device by monolithically integrating thin-film transistors(TFTs) with light emitting diodes(LEDs) and forming active layers of the LEDs and the semiconductor layers of the TFTs of org. materials. SOLUTION: The monolithically integrated org. TFTs and org. LEDs 200 are formed by first depositing a conductive layer on transparent substrate 205. The layer acts both as the gate 215 of the electric field effect (TFT) (FET) 201 and the anode 216 of the LED 202. Next, a dielectric layer 220 of the FET 201 is formed. After the conductive layer and dielectric layer 220 are formed on the substrate 205, the source electrode 225 and drain electrode 226 of the FET 201 or the semiconductor material 230 of the FET is deposited. Since the semiconductor material 230 is not used as a hole transfer body, the layer of a hole transfer body 235 is formed in order to obtain necessary characteristics. An electron transfer body/emitter layer 240 is deposited on the hole transfer body 235 and in succession, a cathode 245 is deposited to complete the LED 202.

Abstract: PROBLEM TO BE SOLVED: To improve the performance of a thermally controllable grating by housing the thermally controllable fiber grating in a heat insulating tube. SOLUTION: A fiber equipped with a thermally controllable grating 11 is housed in a tube 12 such as a cylinder so that heat is insulated. The diameter of the tube 12 is controlled to be large enough to produce a proper space between the tube 12 and the fiber 10 and to avoid the contact of the grating 11 with the tube 12 but to be small enough to avoid generation of large air flow near the grating 11. The inner diameter of the tube 12 is preferably 1 cm or less. The tube 12 is sealed on both ends with elastic (rubber) stoppers 13, 14. A heat reflective coating may be applied on the tube 12 to obtain a better result. By inserting capillary tubes 15, 16 through the stoppers 13, 14, respectively, openings to pass the fiber 10 through the tube 12 are obtd.

Abstract: PROBLEM TO BE SOLVED: To obtain an optical diffraction grating device having an adjustable chirp. SOLUTION: The optical waveguide diffraction grating having an adjustable chirp includes a waveguide diffraction grating thermally brought into contact with an electrically controllable heat converting substrate whose temperature is changed along the length of the diffraction grating (A). The heat converting substrate can generate heat on a fiber, or remove heat from the fiber, and temperature slope can be generated along the diffraction grating. In an execution example, the heat converting substrate is constituted as a resistance film whose local resistance is changed along the length of the diffraction grating (B). Currents running through the thin film can generate the temperature slope along the diffraction grating almost proportional to the local resistance of the thin film, and the size of the chirp can be adjusted by the currents. Thus, this obtained device can be made simple, compact, and efficiently power.

Abstract: PROBLEM TO BE SOLVED: To optimize the performance of an optical communication system by providing a data maintenance monitor, and adjusting dispersion elements so that the performance of this system is optimized, and deciding the distribution of grating according to the strength of added currents, detecting the maintenance of transmitted data and controlling the currents to be added to the grating. SOLUTION: Each automatic distribution compensating module 20 is provided with a variable distribution compensator 30, a data maintenance monitor 31 and a feedback network 32, and the monitor 31 adjusts the distribution compensator 30 through the feedback network 32 so that the performance of this system is optimized. Part of a signal on a transmission fiber path 11 is sampled, for example, by a tap 34, and this signals is analyzed so that the scale of the maintenance of the transmitted data can be obtained, and a feedback signal for controlling a variable distribution compensation grating 33 can be obtained from this scale. In the variable distribution compensator 30, a signal light from the transmission fiber 11 is directed to the variable distribution compensation grating 33.

Abstract: PROBLEM TO BE SOLVED: To make it possible to produce a grating device having a wide band width, freely regulatable dispersibility and amplitude responsiveness by adding an extrinsic gradient to a waveguide and changing the range of the chirp in an intrinsic chirp type grating region. SOLUTION: The grating device 10 is manufactured by providing the device with the waveguide of a certain length like an optical fiber 11 having a grating region 12 in the waveguide. The grating region 12 has nonuniformly parted fluctuation parts and reflects the intrinsic chirp type grating. When the extrinsic gradient or force is impressed to the waveguide, the range of the chirp changes. First and second magnetic elements 15a and 15b attracts or repels to or from each other to introduce an elastic strain to the optical fiber 11 of the grating region. A gradient forming main body 14 is mounted on the optical fiber 11. As a result, the device which can include the grating of a certain range and the wide band width may be formed by using low temperature and weak force. The regulation of the dispersibility and amplitude responsiveness of the grating is possible as well.

Abstract: PROBLEM TO BE SOLVED: To provide an optical waveguide grating device having an adjustable optical spacing profile. SOLUTION: The optical waveguide grating having the adjustable optical spacing profile is provided with a waveguide grating coming into thermal contact with one or more resistive film coatings. The coating is extended along the length direction of the grating and its local resistance is changed in accordance with the length of the grating. Since a plurality of overlapping coatings are chosen in a certain example, the variation values of respective resistance values are made different and various heat generation profiles are influenced by the control of each individual coating. Different heat generating profiles successively and proportionally change the geometric spacing and local refractive index of the grating along the length direction of the grating, so that a required adjustable optical spacing profile can be provided. In another example, a resistance film is used on the basis of heating variation to be suddenly or periodically changed.

Abstract: PROBLEM TO BE SOLVED: To make it possible to use an optical grating device as a device for regulatable dispersion correction and to selectively change the characteristics and performance thereof by constituting the device in such a manner that the spacings between grating elements can be changed by a variable coating when strain in an axial direction is impressed to a waveguide. SOLUTION: A movable magnet 15a is directly added to the fiber coating 14 adjacently to a grating region in order to induce the strain in the fiber. A magnet 15b which does not move is added to a fixed base material 16 or a guide rail in a bond region 13b. At this time, the magnet 15a induces the shift in a wavelength distribution having a possibility useful to some of applications of dispersion correction. When the strain in the axial direction is impressed to the waveguide by the magnet moment induced in the magnets 15a and 15b, the spacings between the grating elements may be changed by the variable coating.
