“…more stringent and it is more challenging to fulfill it in conventional bulk materials and waveguide designs. Multiple zero-dispersion points between the pump and signal wavelengths are required to meet the existence condition and a strategy to achieve it is by employing a recently studied sandwich waveguide structure [37].…”

By identifying the similarities between the coupled-wave equations and the parametrically driven nonlinear Schrödinger equation, we for the first time unveil the existence condition of quadratic solitons in continuouswave pumped singly resonant degenerate optical parametric oscillators (SR-DOPOs). Compared to the previously explored doubly resonant DOPOs, quadratic solitons in SR-DOPOs are advantageous in their robustness against perturbations induced by dispersion of the effective third-order nonlinearity and temporal walk-off between the signal and the pump. Terahertz comb bandwidth and femtosecond pulse duration are attainable in an example periodically poled Lithium niobate waveguide resonator in the short-wave infrared. The working principle can be extended to other material platforms, making it a competitive ultrashort pulse and broadband comb source architecture at the mid-infrared.

“…As a result, the power efficiency of optical devices can be improved. In addition, multiple zero dispersion points which can be obtained in hybrid MNPWs in the MIR regime is an important technology for flattened and broadband MIR SC generation [233,234]. The nano-LiNbO 3 MNPW has become a research highlight because it can be flexibly controlled by multi-physics fields such as acoustic, thermal, and electric fields [235,236].…”

χ (3) nonlinearity enables ultrafast femtosecond scale light-to-light coupling and manipulation of intensity, phase, and frequency. χ (3) nonlinear functionality in micro-and nanoscale photonic waveguides can potentially replace bulky fiber platforms for many applications. In this Review, we summarize and comment on the progress on χ (3) nonlinearity in chip-scale photonic platforms, including several focused hot topics such as broadband and coherent sources in the new bands, nonlinear pulse shaping, and all-optical signal processing. An outlook of challenges and prospects on this hot research field is given at the end.

“…Though fourth-order dispersion 15,21 and even higher-order dispersion 63 have been adopted for extending the zero-GVD working point, an improvement in comb bandwidth has not yet been witnessed. Flat dispersion has been achieved in a similar way in a vertical-slot waveguide, 64 but the heterogeneous implementation was less attractive compared with our monolithic approach. The corresponding single-soliton comb spectra obtained by solving the LLE are given in Fig.…”

Stretching the spectra of Kerr frequency combs with self-adaptive boundary silicon waveguides

Dispersion engineering of optical waveguides is among the most important steps in enabling the realization of Kerr optical frequency combs. A recurring problem is the limited bandwidth in which the nonlinear phase matching condition is satisfied, due to the dispersion of the waveguide. This limitation is particularly stringent in high-index-contrast technologies such as silicon-on-insulator. We propose a general approach to stretch the bandwidth of Kerr frequency combs based on subwavelength engineering of single-mode waveguides with self-adaptive boundaries. The wideband flattened dispersion operation comes from the particular property of the waveguide optical mode that automatically self-adapts its spatial profile at different wavelengths to slightly different effective spatial spans determined by its effective index values. This flattened dispersion relies on the squeezing of small normal-dispersion regions between two anomalous spectral zones, which enables it to achieve two Cherenkov radiation points and substantially broaden the comb, achieving a bandwidth between 2.2 and 3.4 μm wavelength. This strategy opens up a design space for trimming the spectra of Kerr frequency combs using high-index-contrast platforms and can provide benefits to various nonlinear applications in which the manipulation of energy spacing and phase matching are pivotal.
