Abstract

In this paper, a kind of free-space optical switch based on polarization was proposed. Its operation principle was described in detail. Based on this method, some basic types of optical switches were presented, such as 1 X 2, 2 X 1 and 2 X 2 optical switches. Then, taken as an example, the 1 X 2 type was tested to give the experiment performance of this kind of free-space optical switch based on polarization. Its insertion loss was less than 3 dB, crosstalk between different channels were as low as -32 dB, and its switching time was about 2 ms. It showed that this kind of optical switches could be well used in OADM for optical networks protection and reconfigurration. Also its disadvantages were discussed at the end of this paper.
