  • Patent number: 10054748
    Abstract: An optical assembly includes a combination of laser sources emitting radiation, focused by a combination of lenses into optical waveguides. The optical waveguide and the laser source are permanently attached to a common carrier, while at least one of the lenses is attached to a holder that is an integral part of the carrier, but is free to move initially. Micromechanical techniques are used to adjust the position of the lens and holder, and then fix the holder it into place permanently using integrated heaters with solder.

  • Patent number: 9885836
    Abstract: A collimator lens 311 emits by converting a light signal from an optical fiber cable 20 to a collimated light, for example. The collimator lens 311 is retained in a plug housing 315 coupled to a reception side optical connector of the light signal. When the plug housing 315 is not coupled to the reception side optical connector, the pressing portion 313a sets the position of the collimator lens 311 at a position at which the emitted light signal has a predetermined divergence angle. When the optical connectors of the transmission side and the reception side are not connected, the light signal emitted from the optical connector of the transmission side is dispersed, and therefore emission of the light signal is prevented from giving a bad influence to a visual perception function or the like.

  • Patent number: 9557499
    Abstract: Techniques for coupling light from a waveguide array to a single mode fiber array are described. In an embodiment, lateral misalignment of an array of focusing lenses and an array of optical fiber ferrules held into alignment by a lens holder sub-assembly is compensated by tilting the lens holder sub-assembly with respect to the propagation axis of the light being coupled by the lens holder-subassembly. Since the amount of tilt can be adjusted according to the degree of lateral misalignment, lens holder sub-assemblies manufactured with varying degrees of misalignment may be utilized to couple light into single mode fiber-optic cable. In addition, the same technique can also be used to compensate for other defects as well, such as angular errors in manufacturing or placement of a turning mirror or prism used to direct light into the lens holder sub-assembly.
