摘要： A method of manufacturing a side-coupling structure, associated with coupling an aiming beam from an aiming beam fiber into a laser beam fiber, may include removing a coating from a section of the laser beam fiber and removing a coating from a section of the aiming beam fiber. The method may further include bringing the section of the aiming beam fiber in physical contact with the section of the laser beam fiber in order to create the side-coupling structure. The method may further include recoating the section of the laser beam fiber and the section of the aiming beam fiber in order to coat the side-coupling structure.

摘要： Methods, apparatus, and systems for active saturable absorbance of an optical beam. An active saturable absorber may comprise an optical input to receive an optical beam, and one or more lengths of fiber between the optical input and an optical output. At least one of the lengths of fiber comprises a confinement region that is optically coupled to the output. The active saturable absorber may further comprise an optical detector to sense a characteristic of the optical beam, such as power. The active saturable absorber may further comprise a perturbation device to modulate, through action upon the one or more lengths of fiber, a transmittance of the beam through a fiber confinement region from a lower transmittance level to a higher transmittance level based on an indication of the characteristic sensed while the transmittance level is low.

摘要： An optical waveguide device includes: a mode splitter including a main waveguide in which lights can be propagated in at least two propagation modes with different propagation orders and a subsidiary waveguide which includes a coupling section disposed in parallel with the main waveguide at a certain distance away from the main waveguide so as to constitute a directional coupler and is capable of splitting at least one propagation mode out of the two or more propagation modes from the main waveguide. Also, ncore/ncladding which is a refractive index ratio between a core and a cladding which constitute the main waveguide and the subsidiary waveguide is in a range of 101% to 250%.

摘要： An optical waveguide mode transformer device includes a first optical waveguide bend structure and a second optical waveguide bend structure formed by vertically stacked multiple layers of light transparent media. One of the core layers of the optical waveguide bends has a higher refractive index and the other has a lower refractive index. The waveguide centers of the two optical bend structures are de-centered. The bend structure having higher refractive index core layer terminates at a location of the mode transformer device between its two ends. With proper bend structure design, the optical power can be completely transferred from the high index waveguide to the low index waveguide with the help of such vertical stacked de-centered bend structure.
