Abstract
We describe a micromechanically-tunable polarization rotator for photonic integrated circuits. A suspended micro-mechanical (MEMS) beam enables symmetry-breaking mode perturbation and polarization rotation. Vertical actuation results in tunable rotation over 90 degrees and full TE-TM conversion.
