Paper Abstract

A micro high-speed 1×2 magneto-optic switch, which is used in high-speed all-optical network (AON), is designed and analyzed. The theoretical and experimental analysis of the micro high-speed magneto-optic switch mainly involves the parts of optical route, nanosecond impulser and high-speed magnetic field etc. The study of optical route covers design scheme of polarization optical route in the optical switch, the performance analysis of magneto-optic crystal by using Faraday Effect. The research of nanosecond impulser involves the design, simulation and test of electronic circuit diagram of nanosecond pulse. The analysis of high-speed magnetic field consists of magnetic path design in Faraday rotator and analysis of high-speed magnetic field etc. The nanosecond current pulse transient from nanosecond impulser is used to switch the magnetization of the magneto-optic crystal, which propagates a 1550nm optical beam. The experiment results state that nanosecond impulser can output the current pulse with impulse amplitude 10~60V and impulse width 10~ 100ns. The optical beam can be stably switched and the switching time is less than 1μs currently.
