1. An electro-optic device, comprising:
an electro-optic component including electro-optic material having a slab and a ridge portion, the electro-optic component being implemented on a first portion of the slab and a portion of the ridge portion, the first portion of the slab having a first height, the ridge portion having a second height greater than the first height, wherein the electro-optic component includes an asymmetric y-splitter including a first branch and a second branch, wherein the asymmetric y-splitter splits the slab into a first slab and a second slab and the ridge into a first ridge and a second ridge, wherein the first branch includes the first slab and the first ridge, wherein the second branch includes the second slab and the second ridge; and
a passive functionality component implemented on a second portion of the slab, wherein the passive functionality component has a third height, and wherein the third height is less than or equal to the first height.
