Abstract

The optical current-controlled oscillator (CCO) is an all-optical device capable of producing frequency-tunable intensity oscillations (subcarriers) on an optical carrier without any active radio frequency/microwave components. From a dynamic point of view, the CCO is a nonlinear optical system supporting the Hopf bifurcation and operating in the periodic orbit regime. This article presents the theoretical foundation for the optical CCO and its applications in optical communications involving subcarriers. Using one embodiment of the optical CCO employing a two-section Fabry-Perot laser diode, we present the static and modulation characteristics of the periodic-orbit subcarrier of the optical CCO. The performance of CCO-based all-optical subcarrier optical communication system is estimated using representative device parameters. The relationship between the capacity of CCO-based communication networks and the frequency-tuning range of the CCO is also established. (C) 1998 American Institute of Physics.
