    摘要： The invention envisages control devices acting on the laser to vary in time the electron/photon interaction, means proceeding to a State I in which they alter the optimal conditions for laser amplification; and a State II in which that reestablish said optimal conditions, which control devices permit the improvement of the peak amplitude and stability of the laser pulses and the rate and stability of the pulse period. According to another aspect of this invention, the two states are alternated, preferably periodically or almost periodically. The duration of State I should be selected by comparison with the characteristics of the electron packet and, in particular of the relaxation time observed for said packet. If the duration of State II is set to a value to be comparable to or longer than the electron relaxation time, the peak amplitude of the laser pulses is increased. The duration of State II should be selected by comparison with the natural macropulse width. If the duration of the State II is set to a value shorter than the natural duration of the laser macropulses, the repetition rate of the laser pulses can be increased.

    摘要： Embodiments of a wavelength tunable optical coupler, integrated optical components, and lasers are disclosed. The tunable optical coupler, the integrated optical components, and the lasers include thermo-optic organic material that has an index of refraction which can quickly vary in response to changes in temperature. By controlling the temperature in the thermo-optic organic material through the use of heaters or coolers, the optical coupler, the integrated optical components, and the lasers can be quickly and selectively tuned over a broad range of wavelengths with high spectral selectivity.

    摘要： An optical device includes at least a first and second electrical conductors. At least one optical layer overlies at least a portion of the first and second electrical conductors. An applicator is positioned proximate to said at least one optical layer to selectively redirect light from the optical layer. An electrical coupling path between said at least one applicator and one of said first or second electrical conductors, at least a portion of the coupling path traversing said at least one optical layer. At least one optical waveguide may be formed in an optical layer above said electrical conductors. A feature is located to receive light redirected by the applicator and at least one electrical coupling path, which may be included in said feature, couples the applicator and at least one of said plurality of conductors. In a further aspect, a method for manufacturing an optical device is disclosed. The method comprises the steps of: providing a substrate; constructing at least a first electrical conductor in a first substantially planar layer; forming an optical guiding structure in an optical layer; constructing at least one applicator capable of redirecting optical energy; constructing a feature; and electrically coupling said applicator and said at least first electrical conductor.

    摘要： An optical beam routing apparatus is constructed of solid material in which is embedded a beam routing array structure (1370) which has at least a first waveguide segment (1376) traversing the solid material along a plane, second waveguide segments (1378) traversing the solid material along the same plane and encountering the first waveguide segment at a plurality of intersections, electrically-controlled gratings 1372, 1373) disposed transverse to the intersections to controllably reflect optical energy between the first waveguide segment and the second waveguide segments, and optical reflectors (1374, 1375) at selected locations in line with the second waveguide segments (1378) for projecting optical energy into and/or out of the plane from a selected position (1382) on an-out-of-plane medium which might contain optically readable or writable information, such as a disc. Electrodes at the intersections and the electrically-controllable gratings (1372, 1373) disposed transverse of the intersections and controlled by the electrodes controllably reflect optical energy between the first waveguide segment and the second waveguide segment upon application of a controlled electric field at the electrodes.

    摘要： A thermally wavelength tunable laser includes a core, the core including more than one diffraction grating, and thermo-optical material adjacent to each diffraction grating. By selectively changing the temperature and hence the refractive index in the thermo-optical material adjacent to a chosen diffraction grating, the chosen diffraction grating can be tuned over a selected wavelength range. By selecting different diffraction gratings, different, non-overlapping wavelength ranges can be selected and the laser can be tuned over a broad range of wavelengths.
