A PLC-based LP 11 mode rotator is proposed. The proposed mode rotator is composed of a waveguide with a trench that provides asymmetry of the waveguide. Numerical simulations show that converting LP 11a (LP 11b ) mode to LP 11b (LP 11a ) mode can be achieved with high conversion efficiency (more than 90%) and little polarization dependence over a wide wavelength range from 1450 nm to 1650 nm. In addition, we fabricate the proposed LP 11 mode rotator using silica-based PLC. It is confirmed that the fabricated mode rotator can convert LP 11a mode to LP 11b mode over a wide wavelength range.
