Defect modes in microring resonator arrays fabricated in silicon-on-insulator technology

We show experimentatly the existence of defect modes in mutually coupled microring resonator array fabricated in silicon-on-insulator technology. The movements of donor-like and acceptor-like modes are demonstrated for various defect lengths and in a good agreement with earlier theoretical prediction

Box-like filter response of two-dimensional array of microring resonator fabricated in silicon-on-insulator technology

We show theoretically and demonstrate experimentally that box-like response can be obtained using 2D arrays of microring resonator. The box-like response is manifested from the complementary photonic bandgap properties of the column and row configurations. The observed sidelobe suppression is similar to 10dB, while the usable bandwidth can be as high as 500 to 750 GHz
