| contents | Dispersion management of few-cycle pulses is crucial for ultrafast optics and photonics. Often, nontrivial dispersion is compensated using complex optical systems or minimized through careful design of waveguides. Here, we present dispersion-managed adiabatic frequency conversion enabling efficient downconversion of an 11.1-fs near-IR pulse to an 11.6-fs mid-IR pulse spanning an octave of bandwidth from 2-4 $μ$m. The adiabatic frequency converter is designed to impart a constant group delay over the entire bandwidth, eliminating the need for complex dispersion management and opening a new avenue for dispersion engineering in ultrafast optics and photonics. Notably, dispersion engineering through the position-dependent conversion position of an adiabatic conversion device constitutes an additional mechanism for dispersion control in ultrafast optics and photonics while maintaining high conversion efficiency for broadband pulses. |
