Abstract: Embodiments are disclosed for reduced lane utilization for an optical transceiver. An example optical transceiver apparatus includes at least one optical source and an optical connector. The at least one optical source is attached to a printed circuit board (PCB) and is configured to facilitate communication of optical signals. The PCB comprises an electrical connector electrically connected to the at least one optical source and is configured to facilitate communication of electrical signals. Furthermore, the PCB is attached to a mechanical structure. The optical connector is attached to the mechanical structure and is coupled to the at least one optical source via at least one optical fiber that facilitates transmission of the optical signals.

Abstract: A multi-chip module (MCM-10) includes a substrate (11), one or more photonic chips (14) disposed on the substrate, and an electronic chip (12) disposed on the substrate. The one or more photonic chips include one or more optical channels (22), which are configured to guide propagating optical signals, and two or more photonic modulator-segments (18) coupled to each of the optical channels, each photonic modulator-segment configured to modulate the propagating optical signals responsively to digitally modulated driving electrical signals provided thereto. The electronic chip is configured to generate the digitally modulated driving electrical signals on multiple different lanes (16) of the electronic chip, synchronize the driving electrical signals on the multiple lanes to a same clock, separately control respective phases of the driving electrical signals, fine-tune the voltages of the driving electrical signals on the multiple lanes, and drive the photonic modulator-segments on the photonic chips with the synchronized and phase-controlled driving electrical signals.

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: A reconfigurable and redundant electro-optical connector and corresponding method are provided. The connector may include a first plurality of transducers in communication with a first port and a second plurality of transducers in communication with a second port, the first port and the first transducers defining a first channel and the second port and the second transducers defining a second channel. The connector may include a selective combiner to combine the first optical signals and the second optical signals, and a controller in communication with each of the transducers. The controller may transmit at least a first portion of a first datalink on at least the first channel in a first configuration. The controller may redistribute the first portion of the first datalink onto at least the second channel in a second configuration.

Abstract: An apparatus includes a bank of optical detectors, an input optical filter and a selector. The optical detectors are configured to output respective detection indications in response to detecting a presence of an optical signal. The input optical filter is configured to receive an input optical signal having an input wavelength, and to route the input optical signal to one of the optical detectors in the bank depending on the input wavelength. The selector is configured to select an output wavelength based on the detection indications of the optical detectors, and to cause generation and transmission of an output optical signal at the selected output wavelength.
