Abstract:
Nonlinear photonic crystal ring resonators are suitable mechanisms that can be used for designing optical logic gates and digital structures. In this paper we designed 2 nonlinear resonant rings by adding doped glass rods inside the photonic crystal ring resonator. An optical half adder was designed using these nonlinear photonic crystal ring resonators. We used plane wave expansion and finite difference time domain methods to simulate our optical half adder. The simulations show that when one of the input ports is ON, the normalized optical power at the S is about 90%. The time delay in this case is 7 ps. Also when both the input ports are ON, the normalized optical power at the C is about 155%. The time delay in this case is 8 ps.
