Abstract: An apparatus includes a photodetector and a memristor coupled to the photodetector. The photodetector is configured to receive and convert optical signals to electrical signals to program the memristor to an on or off state. The apparatus further includes a ring resonator coupled to the memristor and configured to modulate light based on the on or off state of the memristor.

Abstract: Systems, devices, and methods are provided for all-optical reconfigurable activation devices for realizing various activations. An example of the systems and methods disclosed herein includes operation of a nonlinear activation device using injection seeding to generate secondary optical signals based on injection locking using a seed signal and an optical power of the seed signal that exceeds a threshold. For example, the system and methods include adjusting a bias applied to an optical source comprising an optically active region positioned between Group III-V semiconductor material and receiving a first optical signal at a first wavelength that injection locks the optical source. The optical source emits a second optical signal at a second wavelength based on injection locking and generates one or more secondary optical signals based on: optical power of the first optical signal and the bias applied to the optical source.
