| Abstract: | A high performance all-optical switch with electro-optic polarization control is present.The all-optical switch is based on the TE-TM mode converter and rectangular fused-silica subwavelength grating for the wavelength of 1550nm.The polarizations of output signal are controlled by TE-TM mode converter,and the output ports are switched by the rectangular subwavelength fused-silica grating.It is shown the crosstalk of switches（i.e.output-1 and output-2） is-72dB and-33dB,respectively.The all-optical switch can be realized rate of nanoseconds and has simple structure,high reliability,low cost and so on.It has a wide range of applications in the all-optical fiber communication network. |
