| 摘要 |
An apparatus comprising a waveguide (204) along a longitudinal axis at a first elevation, an optical splitter (206) coupled to a first edge (206A) of the waveguide along the longitudinal axis, two or more inverse tapers (208) coupled to a second edge (206B) of the optical splitter (206) along the longitudinal axis, and one or more offset inverse tapers (210) that are substantially parallel with the two or more inverse tapers (208), wherein the one or more offset inverse tapers (210) are along the longitudinal axis at a second elevation. |
