We demonstrate that propagation through a silicon microring coupled-resonator optical waveguide can introduce spectral correlations between two or more light sources separated by almost 1 THz over information bandwidths upto 40 GHz.
Intensity and group delay are measured with high spectral resolution in long silicon microring coupled-resonator optical waveguides (CROWs), with the first experimental evidence that coherent oscillations of the coupled resonators constitute the propagating eigenmodes.
We demonstrate intra- and inter-band wavelength conversion enhancement for continuous wave sources in wide-passband coupled resonator optical waveguides (CROWs), compared with their constituent silicon waveguides.
We demonstrate a non-invasive diagnostic method of quantitative infrared (IR) imaging, applied here to a series cascade of microring resonators fabricated in silicon-on-insulator. The IR images contain information on the otherwise inaccessible individual through-ports and the resonators themselves, providing coupling, loss and intensity-enhancement parameters for the individual rings.
Silicon microring coupled-resonator optical waveguides (CROWs) with up to 235 unit cells are fabricated and measured. These are the longest CROW structures made, and both amplitude and group delay variation measurements are reported.
