The results of numerical simulations show that the all-optical trigger behavior with ultra-high on/off ratio can be easily achieved by adjusting the device parameters. To improve and optimize the optical trigger operation, the negative initial delay (the signal pulse before the controlling pulse) and the positive initial delay (the signal pulse after the controlling pulse) are considered for performing the optical trigger operation.
