Slow-light dark solitons in insulator-insulator-metal plasmonic waveguides

摘要

The potential of slow-light propagation in an insulator-insulator-metal plasmonic waveguide is studied. Due to the high dispersion of the device in the frequency region where the signal group velocity is low, slow-light optical pulses broaden in time and intersymbol interference occurs, limiting the achievable data rates and transmission distance. In order to overcome this problem, we analytically and numerically investigate slow dark solitons in the normal dispersion regime of the waveguide. The storing capability of the waveguide is analyzed from an application point of view.
