摘要： A device includes: at least one laser element with light emitting points to output fundamental waves in a one-dimensional array; a wavelength converting element to carry out wavelength conversion of the incident fundamental waves, and to output wavelength converted light rays; and an output mirror to reflect the fundamental waves, and to transmit the wavelength converted light rays resulting from the wavelength conversion by the wavelength converting element. The wavelength converting element is disposed between the laser element and the output mirror, and the distance between the position of a waist of the fundamental waves output from the laser element and the output mirror is set in accordance with a Talbot condition under which the adjacent light emitting points cause phase synchronization with each other.

摘要： A ring optical resonator is formed on a substrate. An outer circumferential surface of the resonator substantially confines one or more circumferential resonant optical modes. The resonator is positioned above a void formed in the substrate and is supported above the void by a portion of a material layer on the substrate that extends radially inward above the void from an outer circumferential edge of the void to the outer circumferential surface of the resonator. An optical waveguide can be integrally formed on the substrate and traverses a portion of the material layer above the void. The optical waveguide and the ring optical resonator are arranged and positioned so as to establish evanescent optical coupling between them. Q-factors of 108 or more have been achieved with a silica resonator and silicon nitride waveguide integrally formed on a silicon substrate.

摘要： A laser waveguide (22) with a tubular wall (24) that conducts laser energy (30) from a near end (23) to a far end (27) of the waveguide. A filler feed wire (36) slides through the hollow center of the waveguide. A laser emitter (40) delivers laser beam energy (30) to a first end of the waveguide within an acceptance angle A. The laser beam may be non-parallel to an axis (25) of the waveguide by at least 20 degrees to provide room for the laser emitter beside the feed wire. The near end of the waveguide may be flared (23C) to accept a laser beam at a greater angle from the axis. The beam exits the waveguide (32) with an annular energy distribution about the feed wire, and may be focused toward the feed wire by a lens (34) having an axial hole (37) for the wire.

摘要： In the prior art, tunable lasers utilizing silicon-based tunable ring filters and III-V semiconductor-based gain regions required the heterogeneous integration of independently formed silicon and III-V semiconductor based optical elements, resulting in large optical devices requiring a complex manufacturing process (e.g., airtight packaging to couple the devices formed on different substrates, precise alignment for the elements, etc.). Embodiments of the invention eliminate the need for bulk optical elements and hermetic packaging, via the use of hybridized III-V/silicon gain regions and silicon optical components, such as silicon wavelength filters and stabilized wavelength references, thereby reducing the size and manufacturing complexity of tunable lasing devices.

Each of the plurality of ring laser systems includes a ring laser to generate a ring laser optical signal and a local waveguide.

摘要： The present invention relates to a plasmonic optical waveguide using plasmonic coupling between a nano-aperture and a nano-particle. The plasmonic optical waveguide includes the nano-aperture formed with an opening of a nano-scale through which light enters; and a single metal nano-particle arranged at the focal point of the nano-aperture to generate plasmon coupling in association with the light output from the nano-aperture. The plasmonic optical waveguide has an effect of forming a small and strong high-intensity high-density light spot of a sub-wavelength size, in which an amplification rate is increased at the output surface of the nano-particle more than a few hundred times compared with the incident light, since the light is transmitted by plasmon coupling generated between the nano-aperture and the nano-particle.
