Some universal relations for coupling of optical power between microresonator and dielectric waveguides are presented. The analytical expressions of filter bandwidth or the full width at half maximum(FWHM), free spectral range and finesse of resonator are derived. The characteristics of the ring microresonator filter are discussed numerically. It is demonstrated that the loss of the ring resonator reduces the peak value of transmission, widens the filter bandwidth, and reduces the finesse of the resonator filter.展开更多

Proper width of MMI is theoretically optimized using beam propagation method （BPM）. An AWG with a 1 6 um width MMI is fabricated experimentally. The measurement results show that the 3 clB bandwidth is 0.62 nm,insertion loss （IS） ranges from 5.2 dB to 7.5 dB,and the crosstalk is less than - 20 dB. The 3dB bandwidth,channel numbers and channel spacing of the AWG agree well with the simulation values.展开更多
