Abstract

A type of configuration with four identical chirped volume Bragg gratings (CVBGs) in parallel combination was proposed to improve dispersion, and the maximum group delay of nanoseconds can be reached at an oblique incidence. The diffraction properties of CVBGs at oblique incidence were simulated with the transfer matrix method. The performance of this configuration on dispersion, including group delay dispersion and cubic dispersion, was well studied with detailed numerical simulation. With optimization of the CVBG structural parameters, including the grating thickness, spatial chirp rate, and refractive index modulation, the configuration can be applied in large dispersion applications.
