摘要
Through analyzing the nonlinear phase feature of the three-mirror G-T cavity, a novel unequal passband interleaver using a Michelson interferometer in which one mirror is replaced by an equally-spaced three-mirror G-T cavity is design by imitation. The device split an input beam with channel spacing of 50GHz into two beams with channel spacing of 100GHz. At -1dB, the odd channel and the even channel have unequal passband for transmission speed of 40Gb/s and 10Gb/s, respectively. The isolation is more than 30dB. All the possible reflection coefficients of the three-mirror G-T cavity with which the interleavers meet the above need of the DWDM system are searched out by optimization of the computer.
