Query: Tunable bandwidth optical rotator   We propose and experimentally demonstrate a novel type of polarization
rotator which is capable of rotating the polarization plane of a linearly
polarized light at any desired angle in either broad or narrow spectral
bandwidth. The rotator comprises an array of standard half-wave plates rotated
at specific angles with respect to their fast-polarization axes. The
performance of the rotator depends on the number of individual half-wave plates
and in this paper we experimentally investigate the performance of two
composite rotators comprising six and ten half-wave plates.
