Abstract
By using mode coupling and lightwave propagation theory
this paper analyzes the transmission characteristics of Mach-Zehnder interferometric optical periodic filter and its application in OFDM transmission systems
then
an modified structure is proposed. The theoretical analysis shows that the modified filter has better characteristics
and can be used in OFDM multi-demultiplexing technology.
