Recent advances in dispersion engineering for mid-infrared photonics

Dispersion engineering in integrated waveguides and microresonators has been intensely studied in recent years. The main focus is to achieve desirable adjustment of dispersion value, slope, bandwidth and flatness, which is important for broadband nonlinear applications. Dispersion has been viewed as a control knob to leverage the parameter space provided by high-index-contrast on-chip devices, enabling strong interactions of far apart frequency components over an octavespanning bandwidth. Here, we review recent advances in dispersion engineering in integrated waveguides and microresonators based on various material platforms, with an emphasis on their applications in mid-infrared (IR) photonics.
