N2 - In views of reconfiguring optical code-division multiple-access (OCDMA) network coder/decoders (codecs), a dynamic signature coding scheme structured over arrayed-wave guide gratings (AWGs) is devised. Such scheme of signature reconfigurations can find applications on enhancing OCDMA network confidentiality. The code reconfiguration can be achieved by exclusively assigning to each network user a set of composite signatures made up of pseudo-orthogonal maximal-length sequence (M-sequence) codes and randomly selecting one among them to represent each user's signature. On the basis of cyclic and periodic characteristics of M-sequence codes compatible with those of the same dimension AWGs, numerical design examples are illustrated throughout the network codecs configuration and operation.
