Patent ID: 11860410
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Optics (Instruments)
Classification: CPC G  H | IPC G

Claim 16:
17. An optical phased array device comprising:
a substrate;
a first oxide layer disposed on the substrate and comprising an insulating transparent oxide;
a first optical element layer disposed on the first oxide layer;
a second optical element layer disposed on the first optical element layer; and
a second oxide layer disposed on the second optical element layer,
wherein the first optical element layer comprises:
an optical waveguide comprising a semiconductor material;
a branch region for splitting one light traveling along the optical waveguide, into pieces of light; and
a phase control region for independently controlling phases of the split pieces of light, and

the second optical element layer comprises:
a light source comprising a compound semiconductor material different from the semiconductor material of the first optical element layer;
an amplifying region for amplifying a magnitude of an optical signal; and
an emission region for emitting the optical signal of which the magnitude is amplified.
