摘要：
A novel 2 X 2 free-space polarization-independent bi-directional fiber optical switch is presented in this paper. A general formula for coupling-loss of fiber collimators is derived. The insertion loss and crosstalk are analyzed in detail. The experiment results indicated that the insertion loss was less than 1.1 dB, the interchannel crosstalk was about 18.5 dB, and the switching time was about 1ms. The new kind of configuration of the optical switch grants the features of few optical components, high compactness, low optical interchannel crosstalk, fast switching speed, polarization insensitivity, and easiness of optical assembly.
