Fig. 8 shows the system transmittance obtained for different ratio of the length of loop1 and loop2. As it SJB3-019A can be seen that ratio of ring length has no effect on transmittance at the resonance point. The line width of transmission is maximum in the case of L1:L2 = 1:1, that is to say, the slow-light frequency range and bandwidth are maximum. Fig. 9 shows the ratio of effective phase shift changing along with ratio of the length of loop1 and loop2. As antibiotic resistance can be seen that when the length of two loops are equal, the changing rate of system effective phase shift is the largest, and the corresponding group index and group delay are also the largest, and therefore, the largest group delay can be obtained.
