Abstract
Optical pulse sources. In one example, the pulse source includes an optical fiber ring resonator with at least one normal dispersion fiber segment characterized by a positive group velocity dispersion (GVD) per unit length and at least one anomalous dispersion fiber segment characterized by a negative GVD per unit length. In another example, the pulse source includes an optical fiber ring resonator with one or more fiber segments having a positive net group velocity dispersion (GVD); and an intracavity spectral filter optically coupled to the one or more fiber segments. The pulse source is configured to generate one or more optical solitons in the optical fiber ring resonator.
Claims23
An optical pulse source comprising:
- a drive unit configured to provide pump light at a drive power;
- an optical fiber ring resonator optically coupled to the drive unit for receiving the pump light, the optical fiber ring resonator comprising:
- at least one normal dispersion fiber segment characterized by a positive group velocity dispersion (GVD) per unit length;
- and
- at least one anomalous dispersion fiber segment characterized by a negative GVD per unit length;
- wherein a drive power of the pump source, a net GVD of the optical fiber ring resonator, and a frequency detuning parameter of the optical fiber ring resonator are configured to generate one or more optical solitons in the optical fiber ring resonator;
- and
- an output optically coupled to the optical fiber ring resonator for out-coupling a portion of each of the one or more optical solitons.
