Abstract: A package assembly includes a circuit substrate, a top-emitting (TE) vertical cavity surface emitting laser (VCSEL) die having a two-dimensional (2D) matrix addressable emitter array, and a driver integrated circuit (IC) having a flip-chip interconnect configuration. The TE-VCSEL die and the driver IC are coupled together to form a die stack that is mounted to the circuit substrate, with the TE-VCSEL die arranged between the driver IC and the circuit substrate. TE-VCSEL die comprises an optical output arranged at a main surface coupled to the driver IC. The optical output is configured to output light generated by one or more emitters of the emitter array. Thus, the TE-VCSEL die is configured to emit light away from the circuit substrate.

The network device may designate the route as a second colored route having a second color, and may advertise the second colored route to a second intermediate network device to cause the second intermediate network device to propagate the second colored route to the ingress network device over a second colored border gateway protocol session.

Abstract: A bottom-emitting vertical-cavity surface-emitting laser (VCSEL) chip may include a VCSEL array including plurality of VCSELs and an integrated optical element including a plurality of lens segments. The integrated optical element may direct beams provided by the plurality of VCSELs to a particular range of angles to create a diffusion pattern using the beams provided by the plurality of VCSELs. A surface of a first lens segment may be sloped to cause a beam from a first VCSEL to be steered at a first angle and a surface of a second (adjacent) lens segment may be sloped to cause a beam from a second VCSEL to be steered at a second angle. A direction of the second angle with respect to a surface of the VCSEL array may be opposite to a direction of the first angle with respect to the surface of the VCSEL array.

Abstract: Different services through Virtual Routing and Forwarding instances (VRFs) are identified without needing a Multiprotocol Label Switching (MPLS) label or a Virtual Extensible Local Area Network (VXLAN) Network Identifier (VNI) by using, for example, different UDP port numbers to identify different connectivity services (e.g., customers, VRFs) when IP-in-IP (also referred to as IP over UDP) is used as a tunneling mechanism (e.g., in the data center).

Abstract: In an embodiment, a data platform receives a query that includes a two-sided N dimensional interval join of first and second input relations, where N>1. The two-sided N dimensional interval join has an interval-join predicate that, in each of N dimensions, compares intervals determined from the first and second input relations. The data platform implements the interval join at least in part by identifying an intermediate relation that includes all combinations of a row from the first input relation and a row from the second input relation where, in each of the N dimensions, the intervals determined from the first and second input relations both overlap a common N dimensional domain region of an input domain of the first and second input relations. The data platform obtains and returns results of the query.

The network device may compute a second update message based on the information regarding the route; determine that the upper utilization threshold for one or more of the peer queues is satisfied; and pause writing the second update message to the peer queues based on the upper utilization threshold being satisfied. The network device may permit the peer network devices to obtain data from corresponding ones of the peer queues.
