Optical buffering scheme based on two-ring resonator system

We propose a scheme based on two-ring resonator system that can realize flat delay and transmission response with delay-bandwidth product (DBP) higher that those achieved in previously proposed schemes. The spectrum flatness and DBP are two key parameters that characterize the maximum number of bits that can be buffered without distortion for certain signal operating bandwidth. Simple time domain simulation shows that our scheme can achieve the same buffering time with 2 to 4 times smaller number of modules, which indicates DBP of 2 to 4 times larger than those of side-coupled ring structure and coupled resonator optical.
