A new method which employs two mirrors produced in one coating run with anti-phase
group delay dispersion (GDD) is proposed to suppress GDD oscillations. The anti-phase …

We report on a novel starting design structure of highly-dispersive mirror (HDM) which
combines quarter-wavelength structure and multi-cavities, introducing more wavelength …

Genetic algorithm was applied for optimization of dispersion properties in semiconductor
Bragg reflectors for applications in femtosecond lasers. Broadband, large negative group …

This paper presents results of measurements of optical absorption in undoped epitaxial
GaAs for photon energies below the band gap. Absorption spectra were determined from …

The optimized nonuniform growth process was used to achieve spatially dependent
reflectivity and dispersions characteristics in a highly dispersive semiconductor mirror. The …

In this paper, we present an approximation intended to find applications in numerical
simulations of optical phenomena in layered structures. The method can be used to avoid …
