Abstract
The effect of self-injection locking of a laser to a nonlinear microresonator is considered. It is shown that an additional detuning arises in the system, depending on the pump power. This effect can contribute to the generation of optical combs in the pull mode, which will increase the stability of the generated signal.
Highlights
Frequency combs are of great importance for many modern applications in science and technology
Previous works [2] show that soliton generation happens in a certain range of normalized detunings with lower boundary being the bistability criterion and upper boundary being the soliton stability criterion where is normalized pump, is the detuning of the generation frequency from the microresonator eigenfrequency, normalized to the mode half-linewidth
The obstacle lies in the temperature drop, the resonator experiences when the pump laser transits from the blue detuned to the red detuned state
Summary
Frequency combs are of great importance for many modern applications in science and technology. Previous works [2] show that soliton generation happens in a certain range of normalized detunings with lower boundary being the bistability criterion and upper boundary being the soliton stability criterion where is normalized pump, is the detuning of the generation frequency from the microresonator eigenfrequency, normalized to the mode half-linewidth (half loaded decay rate). The obstacle lies in the temperature drop, the resonator experiences when the pump laser transits from the blue detuned (high intracavity power) to the red detuned (lower intracavity power) state.
