Abstract
An optoelectronic device includes a photonic component. The photonic component includes an active side, a second side different from the active side, and an optical channel extending from the active side to the second side of the photonic component. The optical channel includes a non-gaseous material configured to transmit light.
Claims8
An optoelectronic device, comprising:
- a first optical channel;
- a photonic component having a recess and comprising a second optical channel optically coupled to the first optical channel, wherein the first optical channel is arranged along an extending direction of the second optical channel;
- a cladding oxide layer covering the second optical channel, wherein a portion of the cladding oxide layer and a portion of the second optical channel are both exposed to the recess, and the first optical channel is partially embedded in the cladding oxide layer and contacting the second optical channel;
- and
- an organic cladding layer covering the first optical channel,
- wherein the second optical channel has a side surface extending between an upper surface and a lower surface and exposed to the recess, wherein an angle formed by the upper surface and the side surface of the second optical channel is about 25 degrees.
