  • Patent number: 11982824
    Abstract: Embodiments of the present disclosure generally relate to optical devices. Specifically, embodiments of the present disclosure relate to optical devices with one or more optical component circuits. The optical devices including one or more optical component circuits prevent the user from exposure to light when a conductive pathway is interrupted via aperture breakage, for example, from the user dropping the substrate, or from the user dropping the optical device. The conductive pathway allows for current to flow from a power source through the apertures and to one or more light sources and, in some embodiments, one or more light detectors. Aperture breakage resulting in the interruption of the conductive pathway prevents current from being provided to the one or more light sources and/or one or more light detectors to prevent (e.g., automatically prevent) light exposure to the user.

  • Patent number: 11982840
    Abstract: The invention relates to a method for laser-based splicing of a glass fiber (1) onto an optical component (3), comprising the following steps: arranging both surfaces to be spliced substantially parallel to each other and at a predefined distance from each other; and aiming a laser beam (4) at the optical component (3). In order to specify an improved method in which the properties of the joining partners are maintained to the greatest extent during splicing, which exhibits high reproducibility and in particular is suitable for splicing joining partners of different cross-sections, the invention proposes that the angle of incidence of the laser beam (4) on the surface of the optical component be between 15° and 45°.

  • Patent number: 11982843
    Abstract: Aspects of the disclosure are drawn to methods for producing a fused connector termination. An exemplary method may include setting a specification requirement to be met by the fused connector termination and applying an amount of heat to a proximal region of an unfused connector termination. The proximal region of the unfused connector termination may include an inner optical fiber coaxially positioned within an outer ferrule, and applying the amount of heat may at least partially fuse the optical fiber to the outer ferrule to form an at least partially fused connector termination. The method may also include imaging the proximal region of the at least partially fused connector termination and determining, based on the imaging, whether the proximal region of the at least partially fused connector termination meets the specification.

  • Patent number: 11982848
    Abstract: An apparatus includes a fiber-optic connector configured to be connected between one or more optical fibers having fiber cores and a photonic integrated circuit (PIC) including vertical-coupling elements. The fiber-optic connector includes a polarization beam splitter and a patterned birefringent plate. The polarization beam splitter splits an incident light beam from a fiber core into first and second beams having first and second polarizations, respectively. The patterned birefringent plate includes a first region (having a first optical birefringence) and a second region (having a second optical birefringence). The difference in the first and second optical birefringence is caused by (i) applying localized heating to the first region without applying localized heating to the second region to cause the first region to have a lower birefringence as compared to the second region, or (ii) applying different amounts of localized heating to the first and second regions to produce different birefringence.
