摘 要：Our recent work on the use of wavelength conversion and dispersive propagation to produce large tunable delays shows great promise for applications that require information to be buffered. In Phase III of the DARPA/DSO slow light program, we propose to extend our work in conversion/dispersion slow light. Our approach will be transparent to OOK and DPSK modulation formats. The frequency conversion will be performed via broadband four-wave mixing (FWM) in Si nanowaveguides. We will develop two different dispersive delay components that are based on optical fiber or on Si waveguides, which will allow us to pursue a communication systems demonstration as well as demonstrating the fundamental ability to achieve significantly longer optical delays than previously achieved in both fiber-based or chipbased systems.
