Paper Abstract
In the paper, a high speed magneto-optic switch based on the Faraday Effect is designed and analyzed. The novel
magneto-optic switch presented in this paper will satisfy high speed transmission and exchange of optical-message
through all-optic network. It consists of three important components as followed novel optical route, Faraday rotator
configuration with ultrafast magnetic field and picosecond impulser. It may switch the optical route by controlling
Faraday rotator which is supplied by picosecond impulser. By the development of the magneto-optic crystal, and
ultrafast magnetic field, the designed magneto-optic switch featured as low insertion loss, low crosstalk, high switching
speed and small bulky size gets ahead of traditional optic switches. As the first part of this paper, a design scheme of
optical route in high speed magneto-optic switch and its experiment analysis will be discussed. Good avalanche effect of
transistor FMMT415 is adopted to generate picosecond pulse signal and then to drive the high speed magnetic field.
Shown by the experiment data, the rising time of the impulse about 1ns, the amplitude of the impulse about 100~500V
are available on the Output end from the picosecond impulser, which can be used as driving current pulse of Faraday
rotator. By using the relationship between the polarization plane rotate direction of polarization light and magnetic
direction, the Faraday rotator is designed.
