摘要： A display may have an array of display pixels that generate an image. A coherent fiber bundle may be mounted on the display pixels. The coherent fiber bundle may have a first surface that is adjacent to the display pixels and a second surface that is visible to a viewer. The coherent fiber bundle may contain fibers that carry light from the first surface to the second surface. The second surface may be planar or may have a central planar region and curved edge regions that run along opposing sides of the central planar region. The fibers may have cross-sectional surface areas with a first aspect ratio on the first surface and a second aspect ratio that is greater than the first aspect ratio on the second surface.

摘要： An optical circuit includes one or more input waveguides, a plurality of output waveguides, and a reflector structure. At least a portion of the reflector structure forms an interface with the one or more input waveguides. The portion of the reflector structure has a smaller refractive index than the one or more input waveguides. An electrical circuit is electrically coupled to the optical circuit. The electrical circuit generates and sends different electrical signals to the reflector structure. In response to the reflector structure receiving the different electrical signals, a carrier concentration level at or near the interface or a temperature at or near the interface changes, such that incident radiation received from the one or more input waveguides is tunably reflected by the reflector structure into a targeted output waveguide of the plurality of output waveguides.

摘要： Embodiments of a thermally modulated photonic switch are presented herein. One embodiment comprises a topology-optimized structure that includes dispersed silicon and silicon dioxide. This topology-optimized structure includes an input waveguide, a first output waveguide, and a second output waveguide. The topology-optimized structure routes a light beam from the input waveguide to the first output waveguide, when the topology-optimized structure is at a first predetermined temperature that causes a refractive index of the silicon in the topology-optimized structure to assume a first predetermined value, and the topology-optimized structure routes a light beam from the input waveguide to the second output waveguide, when the topology-optimized structure is at a second predetermined temperature that causes the refractive index of the silicon in the topology-optimized structure to assume a second predetermined value that is distinct from the first predetermined value.

摘要： Data center interconnections, which encompass WSCs as well as traditional data centers, have become both a bottleneck and a cost/power issue for cloud computing providers, cloud service providers and the users of the cloud generally. Fiber optic technologies already play critical roles in data center operations and will increasingly in the future. The goal is to move data as fast as possible with the lowest latency with the lowest cost and the smallest space consumption on the server blade and throughout the network. Accordingly, it would be beneficial for new fiber optic interconnection architectures to address the traditional hierarchal time-division multiplexed (TDM) routing and interconnection and provide reduced latency, increased flexibility, lower cost, lower power consumption, and provide interconnections exploiting scalable optical modular optically switched interconnection network as well as temporospatial switching fabrics allowing switching speeds below the slowest switching element within the switching fabric.

摘要： An optical switching system comprising a switching cell having first and second fixed-position bus waveguides and a moveable shunt waveguide is disclosed. The first bus waveguide includes an input and a first output. The second bus waveguide includes a second output. When the switching cell is in its unswitched state, the shunt waveguide is not optically coupled with either bus waveguide and a light signal can pass from the input to the first output while remaining in the first bus waveguide. When the switching cell is in its switched state, the shunt waveguide is optically coupled with both bus waveguides such that the light signal is coupled out of the first bus waveguide and into the second bus waveguide via the shunt waveguide. As a result, the light signal can pass from the input to the second output while bypassing the first input.

摘要： A plasmonic switching device and method of providing a plasmonic switching device. An example device includes a resonant cavity and an electromagnetic radiation feed arranged to couple electromagnetic radiation into the resonant cavity and at least one plasmonic mode. The resonant cavity is arranged to be switchable between: a first state in which the resonant cavity has an operational characteristic selected to allow resonance of the electromagnetic radiation at a frequency of the at least one plasmonic mode; and a second state in which the operational characteristic of the resonant cavity is adjusted to inhibit resonance of the electromagnetic radiation at a frequency of the at least one plasmonic mode.
