The important role of parameters in master laser with optical feedback for the elimination of time-delay (TD) signature in semiconductor laser subject to chaotic optical injection is investigated systemically. The experimental results show that TD signature suppressed chaotic signals can be credibly generated by increasing the feedback strength of the master laser, which is quite different from the trends observed in semiconductor laser (SL) with optical feedback. Systematically numerical analysis is also carried out as a validation, and it is shown that with low bias current and strong feedback strength, parameter regions contributing to successful TD suppression are much wider. Furthermore, it is shown that the influence of frequency detuning in TD concealment will change with the increase of feedback strength. All the numerical results are in perfect accordance with experimental observation.

AbstractNonlinear photonic crystal ring resonators are suitable mechanisms that can be used for designing optical logic gates and digital structures. In this paper, we designed two 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.
