WebApr 10, 2024 · We show that ultrathin metasurfaces with a specific multiresonant response can enable simultaneously arbitrarily strong and arbitrarily broadband dispersion compensation, pulse (de)chirping, and compression or broadening. This breakthrough overcomes the fundamental limitations of both conventional nonresonant approaches … WebGiven a Gaussian pulse with central wavelength 550 nm and a HMFW of 300 nm, and let's assume the pulse is transform-limited. I need to get the pulse through 1mm of quartz. I expect group delay dispersion (second order dispersion) to spread in time the wavelengths from each other making the red end arrive sooner then the green then the blue end.

Webposition, that is, introducing spatial chirp, at its fo-cal plane (Fig. 1(c)). The accuracy of pulse shaping depends on the degree of spatial chirp at the focal plane, on which extensive studies have been carried out [2,4,5]. Other applications of spatial chirp in-clude the suppression of longitudinal mode compe-tition [6,7] in the laser design.

WebFinally, the calculator computes the chirp parameter C C and the accumulated group delay dispersion (assuming a Gaussian shape). The chirp parameter is C = \sqrt {\dfrac {T^2} {T_ {min}^2} - 1} C = T min2T 2 − 1 where T T is the 1/e 1/e pulse duration: T = \dfrac {\Delta\tau} {2\sqrt {\log2}} T = 2 log2Δτ WebA linearly chirped Gaussian pulse in a disper-sive medium is completely characterized by the position and (minimum) duration of the unchirped pulse, just as a spatially Gaussian …
