Abstract :
In an optical link, there is a tradeoff between power consumption of transmitter and that of receiver. This letter investigates this tradeoff by developing a power consumption model for the components of the link. The impact of different photonic technologies is studied. A method to minimize the power consumption by optimizing the optical modulation amplitude is discussed.
