| Abstract: | The principle of integrated fiber Mach Zehnder interferometric Add/Drop Multiplexer(ADM) is introduced in the paper.That the output characteristics and channel isolation variation of the all fiber M Z interferometer when the second coupler's k 2z 2 and the excursion of the difference of two arms have different values are primarily analyzed.The theoretical and the numerical simulation results have some directive function for the actual fabrication or use of ADM device. |
