Paper Abstract

This paper presents a novel 4 X 4 free-space polarization- independent bidirectional fiber optical switch based on 2 X 2 optical switch module. The optical architecture of the 4 X 4 optical switch is designed. The routing path for different switching state is analyzed in details. The performance analysis for this 4 X 4 fiber optical switch architecture is derived. The insertion loss of the 4 X 4 optical switch architecture is less than 4.4 dB and the interchannel crosstalk is less than -74 dB. The switch time is in microsecond range. This new kind of architecture of the optical switch grants the features of less optical components, high compactness, low optical interchannel crosstalk, fast switching sped, polarization insensitivity and easiness to optical assembly.
