Carrier reutilization in a coherent optical network

This research presents a novel approach to improving power consumption in a coherent optical network. The rationale of this paper is to examine a method of reutilizing an optical carrier wave at the receiving end of a transport system. This method provides a means to save energy associated with the creation of the carrier wave for the purpose of data transmission at the distant end. In this embodiment, an amplitude shift key modulated signal with homodyne coherent detection is considered. Factors such as comparative power losses and bit-error rates are examined.
