An apparatus and a method for a design and a simulation of an all-optical proteretic bi-stable device. The proteresis is a reversed hysteresis with an interesting characteristic which increases the oscillation frequency of a feed-back system with a relaxation dynamics by reducing the feed-back delay. The calculation of the bi-stable device parameters, a simulation of the theoretical device, and a simulation of the all-optical device are given. Applications of the proteretic device in ultra-high speed oscillations are also disclosed.

All-optical proteretic photonic integrated device

A modulator, including an integrator (), a bistable device (), an adder () and a feedback loop () is provided. A method for converting a continuous time signal to a binary signal is also provided.
