Abstract
Optical devices, polarization rotators, and mode converters are provided. An optical device of the present disclosure includes a polarization rotator and a mode converter. The polarization rotator includes a straight waveguide segment having a first end and a second end, a first widening waveguide segment continuing from the second end, a first tapering waveguide segment continuing from the first widening waveguide segment, a second widening waveguide segment disposed over the first widening waveguide segment, and a second tapering waveguide segment continuing from the second widening waveguide segment. The mode converter includes a third tapering waveguide segment continuing from the second tapering waveguide segment, and a third widening waveguide segment disposed over the third tapering waveguide segment. An output end of the polarization rotator is coupled to an input end of the mode converter.
