Abstract
A light pulse source (), being adapted for generating repetitive optical pulses, comprises a continuous wave (cw) laser () being arranged for providing cw laser light, an optical microresonator () being made of a resonator material, which has a third order (Kerr) nonlinearity and an anomalous resonator dispersion, wherein the cw laser () is arranged for coupling the cw laser light into the optical microresonator (), which, at a predetermined relative detuning of the cw laser () and the optical microresonator (), is capable of including a light field in a soliton state, wherein soliton shaped pulses can be coupled out of the optical microresonator () for providing the repetitive optical pulses, and a tuning device () being arranged for creating and maintaining the predetermined relative detuning of the cw laser () and the optical microresonator () based on a tuning time profile being selected in dependency on a thermal time constant of the optical microresonator () such that the soliton state is achieved in a thermal equilibrium state of the optical microresonator (). Furthermore, a method of generating repetitive optical pulses is described based on soliton shaped pulses coupled out of an optical microresonator () is described.
