Field: Optics (Instruments)
Classification: CPC H | IPC H

Claim 0:
1. One or more devices, each device comprising:
first, second and third elements; wherein
the first element, comprising an optical gain structure and at least one laser cavity mirror structure, couples light to the second element;
the second element, comprising a phase tuner, couples phase tuned light to the third element; and
the third element, comprising an optical resonator with first and second coupler/splitter structures provides a primary optical output exiting the device;

wherein light coupled into the optical resonator through the first coupler/splitter structure and then coupled out of the optical resonator though the first coupler/splitter structure is injected back into the optical gain structure through the second element;
wherein light reaching the second coupler/splitter structure after passage through the first coupler/splitter structure is split into first and second outputs, the first output being coupled back into the resonator, and the second output being coupled out of the optical resonator as the primary optical output exiting the device, no portion of the primary optical output being fed back into the resonator; and
wherein characteristic of the first and second coupler/splitter structures and the optical resonator are selected such that the light injected back into the optical gain structure reduces linewidth, and noise in primary optical output is suppressed.
