  • All-optical proteretic photonic integrated device
    Patent number: 9806697
    Abstract: 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.
    Type: Grant
    Filed: July 1, 2016
    Date of Patent: October 31, 2017
    Assignee: Board of Trustees, Southern Illinois University
    Inventors: Mohammad R. Sayeh, Nima Davoudzadeh Mahboub Sedigh, Mohamad Tafazoli Mehrjerdi
