Abstract :
In the recent past, we have seen evolution of many new classes of multiwavelength optical orthogonal codes (MWOOC´s) for optical code division multiple access (OCDMA). One important characteristic of these codes is that each set follows a cyclic (modulo-m) generation scheme. In this article, a new concept of polarization-accompanied MWOOC´s, based on this scheme, and its implementation is proposed. The method is based on HiBi FBG in opposition to the normal FBG in the traditional implementation.
