“…Figure 4(c) where the pump oscillates at 1569nm). Engineering the dispersion is indeed recognized as a fundamental and challenging problem in resonators [33]. In our device this issue is minimized, as the properties of the material and waveguide dimensions were engineered to reduce the material dispersion near = 1550nm, with an anomalous group velocity dispersion of the order of 10 ps 2 /km in the middle of the C-band.…”

Abstract: We report a novel geometry for OPOs based on nonlinear microcavity resonators. This approach relies on a self-locked scheme that enables OPO emission without the need for thermal locking of the pump laser to the microcavity resonance. By exploiting a CMOS-compatible microring resonator, we achieve oscillation featured by a complete absence of "shutting down", i.e. the self-terminating behavior that is a very common and detrimental occurrence in externally pumped OPOs. Further, our scheme consistently produces very wide bandwidth (>300nm, limited by our experimental set-up) combs that oscillate at a spacing equal to the FSR of the micro cavity resonance.

We show that broad periodic waveguides operating at the Littrow regime can form series of modes with a negative dispersion in their spacing (dFSR / dω > 0, FSR = Free Spectral Range), thanks to samples with extended range. We provide an analysis of this experimental FSR based on a nearly analytical consideration. For frequency combs, a uniform FSR (dispersion free) can be attained at any desirable frequency in the range λ = 1.5 -4.3 µm for a silicon resonator.

“…reducing the mode volume by making oblate toroidal resonators [42,238] or by shaping the resonators as a low contrast protrusions on a cylindrical preform [239,240]. In general, suggested methods of global GVD manipulation for Kerr frequency comb generation include i) selection of different mode families for dispersion optimization [241][242][243], ii) modification of the resonator morphology [173,203,232,[244][245][246][247][248][249][250][251][252], and iii) development of composite resonators or resonators with spatially inhomogeneous material properties [134,209,246,[253][254][255][256][257].…”

Optical frequency combs have become indispensable in astronomical measurements, biological fingerprinting, optical metrology, and radio frequency photonic signal generation. Recently demonstrated microring resonator-based Kerr frequency combs point the way towards chip scale optical frequency comb generator retaining major properties of the lab scale devices. This technique is promising for integrated miniature radiofrequency and microwave sources, atomic clocks, optical references and femtosecond pulse generators. Here we present Kerr frequency comb development in a historical perspective emphasizing its similarities and differences with other physical phenomena. We elucidate fundamental principles and describe practical implementations of Kerr comb oscillators, highlighting associated solved and unsolved problems.
