英文摘要	Conference Name:Conference on Passive Components and Fiber-Based Devices II. Conference Address: Shanghai, PEOPLES R CHINA. Time:NOV 07-10, 2005.; Magneto-optic switch has been widely researched due to its capabilities handling large beam cross sections, operating at low voltages, featured as low insertion loss and intrinsic non-reciprocity. However, the switching speed is rather slow: switching time of available magneto-optics switches are of hundreds microseconds. Previously, we developed a novel type high speed magneto-optic switch based on Faraday rotation effect of light in yttrium-iron-garnet (YIG). The switch shows its good performance and high reliabilities. However, it had some disadvantages: 1) Although it was polarization independently designed for the insertion loss, some dependence about 0.5dB was observed due to the components' misalignments since it has many components and adjustment points; 2) Faraday rotator assembly designed by using double YIG rods with diameter 3 mm require much higher switching current to rotate the light by 90 degrees. And the heat generated when operating may also affect the YIG performance. 3) The narrow and sharp pulse width of nanosecond trigger impulse signal generated with short duration can't accumulate the high speed switching magnetic field large enough to drive the YIG reach saturation magnetic field within a trigger period. In this paper, we mainly devote to design an improved switch featured as compact optical route, much more effective Faraday rotator assembly and nanosecond trigger impulse signal with wider pulse width.
