All-optical proteretic (reversed-hysteretic) bi-stable device

In this paper, we report for the first time a design and simulation (via VPIphotonics) 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 discussed.
