摘要： A broadband light source device for creating broadband light pulses includes a hollow-core fiber and a pump laser source device. The hollow-core fiber is configured to create the broadband light pulses by an optical non-linear broadening of pump laser pulses. The hollow-core fiber includes a filling gas, an axial hollow light guiding fiber core configured to support core modes of a guided light field, and an inner fiber structure surrounding the fiber core and configured to support transverse wall modes of the guided light field. The pump laser source device is configured to create and provide the pump laser pulses at an input side of the hollow-core fiber. The transverse wall modes include a fundamental transverse wall mode and second and higher order transverse wall modes.

摘要： A light source for an imaging system. The light source includes a microresonator laser array having opposing mirrors arranged substantially parallel to one another. A laser gain medium is between the opposing mirrors. An array of microrefractive elements is arranged to stabilize the microresonator. A pump laser's output is shaped by a lens that directs it toward the micro-resonator laser array. An output lens directs a plurality of laser beams from the microresonator laser array to be incoherently combined at an object to be illuminated.

摘要： An optical resonator system comprises an optical resonator (30) and means (32, 42, 44) for coupling into the resonator counterpropagating waves at total intensities such as to produce a non-linear interaction between the first and second waves whereby to break the symmetry to establish different resonant frequencies between the first and second counterpropagating waves whereby to produce different optical effects in the opposite directions. A common light source, e.g. a laser 32, is employed with an amplifier 40 and a modulator 50, or different light sources can be employed.

摘要： Disclosed is an ultrafast optical switching device based on black phosphorus, including a first channel to generate a first laser which is a continuous wave of a first wavelength, a second channel to generate a second laser which is a continuous wave of a second wavelength different from the first wavelength, a modulator to modulate the second laser generated by the second channel into a pump signal, a first and a second wavelength tunable filters to change wavelengths of the first laser and the second laser, respectively, a directional coupler to couple the first laser and the second laser, and an optical element to control the first and second lasers coupled by the directional coupler by means of nonlinearity and an evanescent field of black phosphorus. Accordingly, volume and size of an ultrafast optical switching device may be reduced, and a data processing rate may be improved.

摘要： A method of manufacturing a wavelength conversion element can control a formation process of a polarization inversion structure with single crystalline magnesium-doped lithium niobate having a congruent composition, and can stably manufacture wavelength conversion elements having high conversion efficiency. The method involves forming periodic electrodes on the +z face of an MgLN substrate and forming an opposite electrode on the −z face of the MgLN substrate; heat-treating the substrate after forming the periodic electrodes and the opposite electrode; and applying a pulsed electric field between the periodic electrodes and the opposite electrode while holding the MgLN substrate at a temperature of 100° C. or higher. The wavelength conversion element has a polarization inversion structure formed by applying an electric field to a heat-treated MgLN substrate.

摘要： A light source device includes a light emitting element and a wavelength conversion device. The wavelength conversion device includes a stationary member, a moveable carrier made of a transparent material carrying one or more wavelength conversion materials and moveable relative to the stationary member, and a stationary first filter. The first filter is fixed on the stationary member and disposed adjacent the moveable carrier. The excitation light from the light emitting element passes through the first filter and illuminates the wavelength conversion materials on the moveable carrier. The wavelength conversion materials convert the excitation light into converted light as the output of the light source device. The size of the first filter is smaller than the size of the moveable carrier and smaller than a carrying area of the moveable carrier that carries the wavelength conversion material. A wavelength conversion method using the wavelength conversion device is also described.
