Abstract
A hybrid analog and digital passive optical network based on optical
code division multiple access is presented, and a code generation method is
proposed to increase the number of codes for existing code families with fixed
and ideal in-phase cross correlations. When code families with cyclic properties
are used by this code generation method, compact encoders based on arrayed
waveguide gratings can be used. The corresponding performance for this hybrid
network is also analyzed.
