Abstract

In a dispersion compensator and method of use thereof a polarized beam splitter (PBS) reflects a light beam having a first instance of S-linear polarization to a first quarter-wave-plate which passes the light beam in a first direction. A first reflector reflects the light beam back through the first quarter-wave-plate in a second, opposite direction, whereupon the light beam now has a P-linear polarization, through the PBS to a second quarter-wave-plate which passes the light beam in a first direction. A second reflector reflects the light beam back through the second quarter-wave-plate in a second, opposite direction, whereupon the light beam now has a second instance of S-linear polarization, which is reflected by the PBS. The first or second reflector is a chirped volume Bragg grating (CVBG) that reflects spectral components of the reflected light beam at different depths of propagation of said spectral components in the CVBG.
