Abstract
Optical soliton pulses are generated using a drive unit to provide pump light at a drive power, a passive optical waveguide ring resonator, a spectral filter in the passive optical waveguide ring resonator, and an output to optically couple optical solitons from the passive optical waveguide ring resonator. The drive power, a net group velocity dispersion (GVD) of the passive optical waveguide ring resonator, a frequency detuning parameter of the passive optical waveguide ring resonator, and the spectral filter are configured to generate one or more optical solitons.
