1 micros tunable delay using parametric mixing and optical phase conjugation in Si waveguides.
We demonstrate continuously tunable optical delays as large as 1.1 micros range for 10 Gb/s NRZ optical signals based on four-wave mixing (FWM) process in silicon waveguide. The large delay range is made possible by a novel wavelength-optimized optical phase conjugation scheme, which allows for tunable dispersion compensation to minimize the residual group-velocity dispersion (GVD) for the entire tuning range.
