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.
