Optical tristability using a twin-stripe laser diode

Abstract
Optical tristability is demonstrated with a positive feedback circuit composed of a twin‐stripe laser diode, a pin photodiode, and a transistor. A novel nonlinearity in the current/light characteristics of the twin‐stripe laser diode is the key point in realizing the tristability. By changing the circuit parameters, optical bistability and differential gain characteristics can also be performed.
