Abstract
The invention refers to an optical device for heterodyne interferometry, comprising a chip, a beam splitter, a first waveguide arranged on the chip, light propagating in the first waveguide being guided to the beam splitter, a second waveguide arranged on the chip, light propagating in the second waveguide being guided to and/or from the beam splitter, wherein the beam splitter, the first waveguide, and the second waveguide form part of a Michelson interferometer, wherein the first waveguide and the second waveguide at least partially form two arms of the Michelson interferometer, and wherein two further arms of the Michelson interferometer are at least partially arranged outside the chip.
Claims23
An optical device for heterodyne interferometry, comprising:
- a chip,
- a beam splitter,
- a first waveguide arranged on the chip and configured to guide light propagating in the first waveguide to the beam splitter, and
- a second waveguide arranged on the chip and configured to guide light propagating in the second waveguide to the beam splitter,
- wherein the beam splitter, the first waveguide, and the second waveguide form part of a Michelson interferometer,
- wherein the first waveguide and the second waveguide at least partially form two arms of the Michelson interferometer,
- wherein two further arms of the Michelson interferometer are at least partially arranged outside the chip, and
- wherein the first waveguide and the second waveguide physically combine at the beam splitter or at a coupler.
