Paper Abstract

In the paper, we have proposed a structure with only one photonic crystal (PC) micro-cavity side-coupled to a PC one-way waveguide to generate strong on-resonance optical delay. According to the coupled mode theory (CMT), the resonator system can maintain a 100% transmission spectrum throughout the complete resonant bandwidth, which is also demonstrated by the numerical results calculated by the finite element method (FEM). As a temporal Gaussian pulse is launched, the simulation results show that the device introduces a strong pulse delay while maintaining total transmission efficiency within the resonant bandwidth, and the resonator structure may be of great significance for making delay lines in optical buffer applications.
