WAVEGUIDE BASED INTERFEROMETER

摘要

An optical waveguide-based interferometer according to an embodiment of the present invention comprises: a first transmission unit which includes a core and a cladding surrounding the core; a detection unit which includes a detection core connected to the core and a detection cladding connected to the cladding; and a second transmission unit which includes a core and a cladding connected to the detection core and cladding, and is symmetric with the first transmission unit arranged on both sides with respect to the detection unit, wherein light is divided and guided from the first transmission unit to the detection unit and the light divided and guided from the detection unit to the second transmission unit is collected. According to the embodiment of the present invention, the optical waveguide-based interferometer can be used without being affected by temperature, and data to be transmitted can be measured with high accuracy without deformation or loss.
