  • 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.

  • Patent number: 11934009
    Abstract: A reinforcing sleeve for collectively reinforcing spliced portions of a plurality of optical fiber core wires disposed side by side includes a heat-shrinkable tube, a heat-meltable member, a tension member, and so on.

A thick portion is provided at a substantially center portion of a width direction of the heat-meltable member. Thus, on a cross section perpendicular to a longitudinal direction of the heat-meltable member, an amount of the heat-meltable member at proximity of the center portion of the width direction of the heat-meltable member is greater than an amount of the heat-meltable member at proximity of the end portions of the width direction of the heat-meltable member. This forms a flow of the heat-meltable member from the center portion toward the end portions in the width direction at the time of melting the heat-meltable member.
