Abstract
An electro-optic device is described. The electro-optic device includes an electro-optic component implemented on an electro-optic material having a slab and a ridge portion. The electro-optic component includes a first portion of the slab and a portion of the ridge portion. The first portion of the slab has a first height. The ridge portion has a second height greater than the first height. A passive functionality component is implemented on a second portion of the slab and is optically coupled with the electro-optic component.
Claims21
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.
An electro-optic device, comprising:
- a modulator including a waveguide and an electrode, the waveguide being formed in at least one electro-optic material having a slab and a ridge, the waveguide including a first portion of the slab and a portion of the ridge, the first portion of the slab having a first height, the ridge having a second height greater than the first height, wherein the waveguide 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;
- a tapered region including a second portion of the ridge and a second portion of the slab, the second portion of the ridge and the second portion of the slab being tapered, the ridge terminating in the tapered region;
- and
- a passive functionality component implemented in a third portion of the slab, the passive functionality component being optically coupled with the modulator, wherein the passive functionality component has a third height, and wherein the third height is less than or equal to the first height.
