Abstract: Embodiments are disclosed for a quantum key distribution enabled intra-datacenter network. An example system includes a first vertical cavity surface emitting laser (VCSEL), a second VCSEL and a network interface controller. The first VCSEL is configured to emit a first optical signal associated with data. The second VCSEL is configured to emit a second optical signal associated with quantum key distribution (QKD). Furthermore, the network interface controller is configured to manage transmission of the first optical signal associated with the first VCSEL and the second optical signal associated with the second VCSEL via an optical communication channel coupled to a network interface module.

Abstract: Disclosed are a testing unit, system, and method for testing and predicting failure of optical receivers. The testing unit and system are configured to apply different values of current, voltage, heat stress, and illumination load on the optical receivers during testing. The test methods are designed to check dark current, photo current, forward voltage, and drift over time of these parameters.

Abstract: An optical coupler and method of assembly are described that provide efficient coupling from the photonic integrated circuit (PIC) waveguide layer to external components, such as optical fibers, VCSELs, photodetectors, and gain blocks, among others. The optical coupler includes a PIC that can be supported by a printed circuit board, an optoelectronic transducer supported by the PIC that can convert between optical signals and corresponding electrical signals, and a coupled waveguide assembly. The coupled waveguide assembly includes a low-index waveguide, a high-index waveguide, and a reflective surface that changes a pathway of the optical signals to direct the optical signals from the optoelectronic transducer into the low-index waveguide or from the low-index waveguide into the optoelectronic transducer.

Abstract: Optical communication modules and associated methods and computer program products for performing network communication security are provided. An example optical module includes a substrate, a first optoelectronic component supported by the substrate configured for operation with optical signals having a first wavelength, and a second optoelectronic component supported by the substrate configured for operation with optical signals having a second wavelength. The module further includes an optical communication medium defining a first end in optical communication with the first optoelectronic component and the second optoelectronic component and a second end. The module also includes security circuitry operably connected with the first optoelectronic component and the second optoelectronic component. The security circuitry determines the presence of a noncompliant component coupled with the optical communication medium at the second end based upon operation of the second optoelectronic component.
