Abstract: Apparatuses, systems, and associated methods are described that provide an optical device with sealed optoelectronic component(s) without impacting effective optical performance of the optical device. An example optical device includes a substrate that defines a first surface and a second surface opposite the first surface. The optical device further includes an optoelectronic component supported by the first surface of the substrate where the optoelectronic component operates with optical signals. The optical device further includes a conformal coating applied to the first surface of the substrate such that at least a portion of the conformal coating is disposed on the optoelectronic component. The conformal coating substantially seals the optoelectronic component from an external environment of the optical device without impacting effective optical performance of the optical device. A thickness of the conformal coating may be determined based upon one or more operating parameters of the optoelectronic component.

Abstract: Processes and devices for continuous compositional grading in photodetectors and electro-absorption modulators (EAM) are provided. An example photodetector includes a multi-layered structure comprising a collector region, an absorber region, a grading layer, and a peripheral layer, all aligned along a detection axis. The grading layer, positioned adjacent to the absorber region, includes multiple sub-layers that define a continuous compositional grading to facilitate smooth carrier transport and reduce recombination. Similarly, an example electro-absorption modulator (EAM) device includes a waveguide mesa formed on a semiconductor substrate, comprising a multi-quantum well (MQW) core layer, upper and lower near-core cladding layers, and upper and lower central cladding layers. The EAM device features both upper and lower grading layers, each positioned between the near-core cladding layers and the adjacent central cladding layers. These grading layers include multiple sub-layers that define a continuous compositional grading, facilitating smooth transitions between the MQW core and surrounding cladding layers.

Abstract: An optical interconnect device and the method of fabricating it are described. The device includes an in-plane laser cavity transmitting a light beam along a first direction, a Franz Keldysh (FK) optical modulator transmitting the light beam along the first direction, a mode-transfer module including a tapered structure disposed after the FK optical modulator along the first direction to enlarge the spot size of the light beam to match an external optical fiber and a universal coupler controlling the light direction. The tapered structure can be made linear or non-linear along the first direction. The universal coupler passes the laser light to an in-plane external optical fiber if the fiber is placed along the first direction, or it is a vertical coupler in the case that the external optical fiber is placed perpendicularly to the substrate surface. The coupler is coated with highly reflective material.

Abstract: Systems, computer program products, and methods are described herein for dynamic reconfiguration of network communications. An example system includes a first network pod including a first set of network ports, a second network pod including a second set of network ports, a set of network cores, and a first intermediate network switch. The first intermediate switch operatively couples the first network pod, the second network pod, and the set of network cores. The first intermediate network switch is configured to selectively establish full bisectional bandwidth data communication between a subset of the set of network cores, a subset of the first set of network ports, and a subset of the second set of network ports.

Abstract: Systems, computer program products, and methods are described herein for machine learning (ML) based network resilience and steering. An example system monitors data traffic across one or more network ports and determines a first data traffic pattern from the data traffic. The system further determines, via a ML subsystem, that the first data traffic pattern is indicative of a security threat to a first network port. In response to determining that the first data traffic pattern is indicative of the security threat to the first network port, the system further isolates the first network port from the one or more network ports.

Abstract: Processes for localized lasering of a lamination stack and graphene-coated printed circuit board (PCB) are disclosed. An example PCB may include a lamination stack, post-lamination, that may further include a core, an adhesive layer, and at least one graphene-metal structure. A top layer of graphene of the graphene-metal structure may have never been grown before the lamination process or may have been removed post-lamination such that a portion of the top layer of graphene is missing. The localized lasering process described herein may grow (for the first time) or re-grow the graphene layer of the exposed portion of the metal layer without adverse effects to the rest of the lamination stack or PCB and while promoting a uniform layer of graphene on the top surface. A process of growing graphene through application of molecular layer and a self-assembled monolayer (SAM), are also described herein.

Abstract: One or more blocks of dynamic random access memory are embedded together with a processor and a data bus on an integrated circuit. The data bus has a bandwidth b for general operation including memory access, the block of dynamic random access memory further requiring data refresh at a refresh rate r. The block thus forms an eDRAM on the integrated circuit, typically an ASIC. A refresh controller embedded with the eDRAM may control refresh by clocking the data bus at a rate higher than the rate of the data bus to accommodate both the required memory access and the required data refresh.
