摘要： The present invention relates to a system for testing the connection paths of a switch fabric by using a spontaneously emitted signal as a test signal. The system includes at least one first module and at least one second module, wherein each one of the second modules is associated to one of the first modules through a connection path in the switch fabric. Each of the first modules is capable of obtaining a respective first measurement of a characteristic of the spontaneously emitted signal supplied to the switch fabric, and each of the second modules is capable of obtaining a respective second measurement of the characteristic of the spontaneously emitted signal. The system further includes a processing module in communication with each of the first and second modules for determining a feature of the optical component based on the first and second measurements.

摘要： Monitoring output power levels of a carrier-effect based switching cell allows phase errors resulting from driving a PIN or PN junction of the switching cell to be dynamically compensated for. The compensation may also allow for compensating of phase errors resulting from the phase imbalance of input couplers as well as phase errors from the waveguide due to fabrication variations. By dynamically compensating for phase errors caused by the driving of the PIN or PN junction, the extinction ratio of the carrier-effect based switching cell can be increased.

摘要： A network planning tool and method for configuring a connection-oriented packet network over a WDM optical network without an optical control layer, such as a SONET/SDH layer. The optical network includes a plurality of optical fibers interconnected through nodes and the connection-oriented packet network, such an Ethernet network, MPLS network, or pseudowire network, includes two or more terminal devices. The method and tool function by building an association between the components of the physical layer, such as the optical fiber, and their geographic location or path. The connection-oriented packet network is configured by building multi-link trunks (MLTs) between terminal devices, where the MLTs are built by aggregating lightpaths that traverse distinctive geographic paths. The MLTs are planned and configured through aggregating lightpaths that traverse incongruent sets of photonic elements. A predetermined target for resiliency to physical failure events may determine the degree of congruence allowed between the sets of photonic elements associated with lightpaths in the same MLT.

摘要： A polarization insensitive optical phased array is provided, for LIDAR or other purposes. A polarization rotator splitter or two-dimensional grating coupler provides two components of co-polarized (e.g. TE-polarized) light. Each component can be routed to a separate optical phased array (OPA) component, and light output of one of the OPA components is rotated in polarization by use of a half wave plate. A polarization controller can receive and control the two components of co-polarized light and then passes the controlled light to the two OPA components. A single OPA component can also be used along with a controller which combines the two components of co-polarized light into a single output, passed to the single OPA component.

摘要： A pixel for creating an optical phase change includes a transparent electrical insulator, a first electrical conductor disposed on the transparent electrical insulator, the first electrical conductor comprising an antenna component and a connector component, an electrical insulator disposed on the first electrical conductor, a transparent semiconductor disposed on the electrical insulator, and a second electrical conductor disposed on the transparent semiconductor. The transparent semiconductor is sufficiently thick to prevent plasmonic resonance from occurring at an interface between the transparent semiconductor and the second electrical conductor.

摘要： A LIDAR or other optical beamsteering apparatus includes an optical switch having a first port and a plurality of second ports. The switch is operated to establish an optical path between the first port and one of the second ports. The first port is connected to a light source or a light detector. Different second ports are connected to different surface/edge couplers. Each of the surface/edge couplers couples light from or to the apparatus in a different respective direction. The surface/edge couplers can be grating couplers. The direction of light coupling is configured due to the orientation of the surface/edge coupler and its grating period, where applicable. Surface/edge couplers can be arranged in a circular or concentric ring pattern. Grating couplers can be elongated.
