Paper Abstract

A new method for channel spacing stabilization to be used in densely packed FDM systems is reported. A periodic step wave signal is applied on a Fabry-Perot interferometer to create a number of equally spaced resonance peaks within one free spectrum range (FSR), and these peaks are used to control the frequency spacing of the transmitter lasers of frequency-division- multiplexing (FDM) systems by time-division-multiplexing (TDM). This new scheme has the capability of frequency-spacing-stabilizing a large number of transmitter lasers and a good frequency spacing stability for practical FDM systems.
