The performance of optical interconnects utilizing non-diffracted beams under different misalignment conditions was analyzed.The signal-to-noise ratio (SNR) was used as the performance index,and the integral optical crosstalk of adjacent channels and detector pre-amplifier thermal noise were treated as the main noise.The results show that the pitch and size of detectors can be used as optimization parameters for maximal misalignment tolerance and a high SNR.Increasing of detector radius and decreasing of spacing between detectors can tolerate greater misalignment,but the spacing cannot be too small in order to achieve an acceptable SNR.Moreover,optical interconnects using non-diffracting beams has the advantage that it is not affected by longitudinal misalignment.
