Abstract: Systems, devices, and methods are provided for all-optical reconfigurable activation devices for realizing various activations functions having normalized output power. The device and systems disclosed herein include an interferometer comprising a first branch formed of a first waveguide and a second branch formed of a second waveguide. A resonator cavity is coupled to the second first waveguide and at least one phase-shift mechanism is coupled to one of the second waveguide and the resonator cavity. The at least one phase-shift mechanism is configured to control biases of the interferometer to achieve a desired activation function at an output of the interferometer, and an optical amplification mechanism is coupled to the output of the interferometer and configured to add optical gain to the desired activation function.

Abstract: Implementations disclosed herein provide semiconductor resonator based optical multiplexers that achieve enhanced bandwidth range of light emitted therefrom. The present disclosure integrates silicon devices into resonator structures, such as micro-ring resonators, that couples a side mode with a lasing mode and resonantly amplifies coupled light to output light having an enhanced bandwidth with respect to the lasing mode. In some examples, the optical multiplexers disclosed herein include a bus waveguide; a first resonator structure optically coupled to the bus waveguide and comprising an optical amplification mechanism that generates light and a single mode filter to force the generated light into single-mode operation; and a second resonator structure optically coupled to the first resonator structure and comprising a phase-tuning mechanism. The phase-tuning mechanism can be controlled to detune phase of light in the second resonator relative to the light in the first resonator.

Abstract: Waveguide shuffle blocks (WSBs) are provided that may incorporate waveguides routed in any pattern to effectuate many-to-many connectivity between optical cables/fibers or other WSBs connected thereto. Such WSBs may be configured in ways that allow the WSBs to be stacked and to achieve effective optical cable/fiber organization. Moreover, such WSBs may include readable tags that can provide information regarding a particular WSB configuration and/or what optical cables/fibers are connected so that network topology can be discovered and monitored. Some WSBs may be configured as wavelength shifting shuffles (WSSs) that allow a particular wavelength(s) of an optical signal(s) to be routed as desired and/or alter a first wavelength associated with a particular optical signal to a second wavelength. In other embodiments WSSs can be configured to allow for wavelength multiplexing/demultiplexing.
