Broadband terahertz dispersion control in hybrid waveguides

Abstract: Dispersion control is a key objective in the field of photonics and spectroscopy, since it enhances non-linear effects by both enabling phase matching and offering slow light generation. In addition, it is essential for frequency comb generation, which requires a phase-lock mechanism that is provided by broadband compensation of group velocity dispersion (GVD). At optical frequencies, there are several well-established concepts for dispersion control such as prism or grating pairs. However, terahertz dispersio… Show more

“…It is for this reason there has been a flurry of activity in the dispersion engineering of QCL cavities, first in the THz [9] and more recently in the mid-infrared [17]. Many dispersion compensation schemes have now been demonstrated, including double-chirped mirrors [9,18,19] and other geometries [17,20].…”

“…Pseudo Wigner-Ville distributions [22][23][24][25] and their modifications are actively used in various fields, such as the dispersion analysis of waveguides [26] and studying oil-in-water flow patterns [27]. We note that various time-frequency filters are employed for eliminating cross-terms in the Wigner-Ville distribution, which is of high importance for the analysis of non-stationary systems.…”
