  • Publication number: 20240146410
    Abstract: A system, method, and device for monitoring a passive optical network (PON). A probe signal is transmitted into the PON. A waypoint device located in the PON proximate to a network waypoint reflects one or more portions of the probe signal in a manner that embeds an address of the waypoint device in a return signal. The address is extracted from the return signal and used to identify the network waypoint associated with the waypoint device. The waypoint device may be selectively perturbed, and the perturbation detected based on changes in the reflected signal to validate the physical identity of the waypoint device.

  • Patent number: 11914193
    Abstract: An optical assembly includes stacked planar lightwave circuit (PLC) members each having a plurality of waveguides in a respective plane, to provide optical connections to two-dimensional arrays of external optical waveguides (e.g., optical fiber cores), with one array including non-coplanar groups of waveguides having group members that are alternately arranged in a lateral direction. An optical assembly may provide optical connections between array of cores having a different pitch and/or orientation to serve as a fanout interface. Methods for fabricating an optical assembly are further provided.

  • Patent number: 11880071
    Abstract: An optical assembly includes stacked first and second planar lightwave circuit (PLC) members each having a plurality of waveguides in respective first and second planes, to provide optical connections between a two-dimensional array and a one-dimensional array of external optical waveguides (e.g., optical fiber cores). Inner faces of first and second PLC members are arranged facing one another and with the first and second planes (corresponding to the pluralities of first and second waveguides, respectively) being non-parallel. An optical assembly may provide optical connections between arrays of cores having a different pitch to serve as a fanout interface. Methods for fabricating an optical assembly are further provided.

  • Patent number: 11577992
    Abstract: A method includes depositing a surface modification layer on sidewalls of a plurality of cavities of a shaped article. The surface modification layer is formed from a glass material including a mobile component. The shaped article is formed from a glass material, a glass ceramic material, or a combination thereof. At least a portion of the mobile component is migrated from the surface modification layer into surface regions of the sidewalls of the shaped article, whereby subsequent to the migration, the surface regions have a reduced annealing point compared to a bulk of the shaped article. The surface modification layer and the surface regions of the sidewalls are reflowed. A surface roughness of the surface modification layer disposed on the sidewalls following the reflowing is less than a surface roughness of the sidewalls prior to the depositing.

  • Patent number: 11529792
    Abstract: Apparatuses and methods for glass laminates having a controlled coefficient of thermal expansion are disclosed. In C one embodiment, a glass laminate includes a glass core having a core thickness (Tcore) and a core coefficient of thermal expansion (CTEcore), a first glass cladding layer and a second glass cladding layer. The first glass cladding layer and the second glass cladding layer are arranged such that the glass core is disposed between the first glass cladding layer and the second glass cladding layer. The first glass cladding layer has a first cladding thickness (Tclad1) and a first clad coefficient of thermal expansion (CTEclad1), and the second glass cladding layer has a second cladding thickness (Tclad2) and a second clad coefficient of thermal expansion (CTEclad2). The glass laminate has a laminate coefficient of thermal expansion (CTEL) within a range of about 35×10?7/° C. to about 90×10?7/° C.
