K. Suyama, T. Ebisawa and S. Komatsu: Comparison of EDOF characteristics between Cubic phase mask and Free-form phase mask for Wavefront Coding, Extended Abstracts (Optics and Photonics Japan 2009) (2009) 406-407. (25pG4)

On the basis of characteristics of a point-to-multipoint optical chaotic communication system, we discuss the effect of the parameter mismatch between the transmitter and receiver laser diodes and propose a new method of detection eavesdropping with reasonable efficiency.
