Due to high switching speed, waveguide opticalswitch will be applied widely to optical switching systems. It is urgent and important to develop waveguide optical switch with high performance.
It can be used to fabricate display devices, high frequency filters, emitting diode, lasers and high-speedopticalswitch. Therefore, it has great USES in both civil and military fields.
Optical soliton is not only an important research aspect, but also it has very important application foreground, which will be the new mold of optical communication and highspeed full-opticalswitch.
