Abstract

The polarization degree of freedom of light plays a crucial role in many classical and quantum technological fields, ranging from sensing [1] and classical communications [2] to quantum information [3]. Many of these applications would benefit enormously from adopting an integrated optics approach, thanks to the unique features of compactness, mechanical stability and precise alignment offered by waveguide-based optical circuits. However, the realization of waveplates with arbitrary oriented optical axes, an essential tool for the manipulation of light polarization, is challenging in integrated optics, due to the difficulty of altering the waveguides simmetry imposed by the fabrication processes [4,5,6].
