The second paragraph in Section 2 of this article was corrected as follows.
In the polarization rotator (Step I), the LN rib waveguide adiabatically widens from a top width of 1.2 to 3.6 μm via a linear taper, such that the effective index of the second-order TE (TE1) mode surpasses that of the fundamental TM (TM0) mode [Fig. 1(c)]. The partially etched structure breaks the vertical symmetry of the waveguide and enables a substantial avoided crossing between the two modes () at a waveguide top width of 2.12 μm as shown in Fig. 1(c). As a result, the input
The text in bold was incorrect in the original published version, and the article was corrected online on 7 December 2021 [1].
