Abstract
In this paper, a novel all optical half subtractor based on threshold switching mechanism was proposed which has one bias port, two input ports and two output ports. The proposed design will be realized by three nonlinear resonant rings and eight waveguides. To analyze and simulate the proposed structure, we employed plane wave expansion (PWE) and finite difference time domain (FDTD) methods. Based on the comparison results, low power consumption, compactness, ultra-fast operation and high contrast ratio are the main advantages of designed all optical half subtractor compared with the previous structures. The ON-OFF contrast ratios for output ports (D and B ports) are about 10.31 dB and 14.96 dB, respectively. Also, the maximum rise, fall and delay times of the proposed structure are about 0.8 ps, 0.45 ps and 1.3 ps, respectively.
