Abstract
A phase modulation device may include two rotated chirped volume Bragg gratings (r-VBGs), where the two r-VBGs are spatially separated along a separation direction oriented at a nonzero degree angle to the grating vectors, and further includes a phase modulator between the two r-VBGs with a spatially non-uniform phase distribution in a plane orthogonal to the separation direction. A first of the two r-VBGs may reflect portions of an input beam propagating towards the phase modulator as spectrally-spread beam. A second of the two r-VBGs may reflect portions of the spectrally-spread beam satisfying the Bragg condition into the incidence direction, where the second r-VBG is positioned to provide that the Bragg condition is satisfied for different wavelengths at different locations of the first r-VBG along the incidence direction to provide that the spectrally-spread beam is spectrally recombined into an output beam.
