| Abstract: | The structure of N ? N optical switch array composed of 2N 1 ? N multimode interference Mach-Zehnder optical switches is reported. The strengths and weak points of this architecture are analyzed. The field transmitting equations of 1 ? N multimode interference optical switch are built by the adoption of the mode field transmitting matrix. The working conditions of optical switch array operated from any input port to any output port are derived. The structure and working conditions of 4?4 optical switch array are discussed based on the above principle and theories. |
