Paper Abstract

By feeding back the output intensity of a laser diode interferoater together with an external modulated light input to the injection current of the laser diode, we have observed the optical bistability and multistability without using cut-off or saturation effect of the gain mediin. We have pointed out that optical chaos can be realized when an appropriate time delay is introduced in the feedback circuit because of the non-l I near property of the interference signal . 1 In this report, optical bistability, multistability, and chaos in active interferometer are presented when the system has a delayed feedback . It is shown that the optical instability occurs at certain corIitions arid this instability is verified to be chaotic.
