"Wide bandwidth, large, and tunable polarization mode dispersion in
multilayered omnidirectional reflectors," Appl. Phys. Lett. 81,
We numerically demonstrate the generation of
large, boradband, and tunable polarization mode disperions (PMD) with
omnidirectionally reflecting dielectric stacks with embedded cavities.
Both first-order and second-order polarization mode dispesion can be
generated by similar configurations. Our examples show that the
first-order PMD can be tuned from 0 to 30 ps over an 80 GHz bandwidth
and second-order PMD from 0 to 50 ps/nm can be generated over a 100
GHz bandwidth. We also shoe that in our configuration there is no
significant modal distortion of the light beam when the beam diameters
exceed 3.5 mm.
