  • Multiple layer optics for light collecting and emitting apparatus
    Patent number: 10784391
    Abstract: A light guide includes a light guide layer having a transversely oriented side-end surface that forms a primary output aperture (exit) for light traveling in a forward propagation direction out of the end surface of the light guide (for, e.g., CPV applications) and, which forms a primary input aperture (entrance) for light traveling in a rearward propagation direction into the end surface of the light guide (for, e.g., illuminator applications).

  • Wide passband wavelength selective switch
    Patent number: 10701465
    Abstract: Methods and apparatus are provided that configure a wider passband for one or more channels of a wavelength selective switch (WSS). When a wider passband route WSS and a normal width passband select switch are used in combination, crosstalk that may be introduced by the wider passband route WSS can be mitigated. The wider passband WSS can provide a passband that allows a maximum bandwidth of signal to pass on a given channel and avoid signal being attenuated at the channel edges, especially when channels have a reduced channel spacing, such as with 50 GHz spacing.

  • Optical fiber coupling reliability
    Patent number: 10670815
    Abstract: Improved optical fiber coupling reliability is realized by improving structures and materials used at the fiber joint. When ceramic ferrules are used at the fiber joint, the penetration of a UV-cured optical adhesive between the ceramic ferrules and the fiber ends is avoided or prevented, while an anti-reflective coating, an uncured optical adhesive, or a refractive index matching gel may be applied between the ceramic ferrules. When glass ferrules are used at the fiber joint, the UV-cured optical adhesive may be applied and fully cured between the glass ferrules and the fiber ends.
