Abstract
Because of their good properties of correlation and security, chaotic sequences have aroused considerable interest in radio CDMA systems. How to generate chaotic sequences and apply them to optical CDMA systems is an interesting and new research topic. A chaotic sequence generator has been designed using Mach-Zehnder interferometers the arm lengths of which are some special values. This generator can generate analogue chaotic sequences which satisfy the Chebyshev map. It can also be used as an encoder of optical CDMA systems to enhance security.
