摘要： A method includes forming a first optical structure with an inverse taper and a separate optical structure on a semiconductor chip. The illustrative method also includes applying a protective structure over the optical structures and patterning the protective structure to expose the separate optical structure. The method further includes removing a portion of the separate optical structure to form a separate trimmed taper separate from, but adjacent to, the first optical structure. The protective structure is then removed from the first optical structure. Apparatuses are also disclosed.

摘要： An apparatus includes a first waveguide configured to receive an input signal. A section of the first waveguide has a length between a first initial point and a first end point. A first polarization rotator is located within the section at a first distance from the first initial point of the section of the first waveguide. A section of a second waveguide is configured to receive the input signal, and has the same length between the second initial point and a second end point. A second polarization rotator is located within the section of the second waveguide at a second distance from the second initial point of the section of the second waveguide. More particularly, a relative distance between the first distance and the second distance is configured to achieve a desired phase delay of an output signal from the first waveguide and an output signal from the second waveguide.
