±π/2-Phase-shift spectral phase encoding for security improvement in the optical code based system

A novel spectral phase encoding scheme by using ±π/2 phase shift in the en/decoding is proposed. The scheme can submerge the code information in the encoded signals well, improving the security against code extraction from the encoded signals. Furthermore, based on the theoretical analysis, the coding performance of the proposed scheme is guaranteed.
