Document Type and Number:
Japanese Patent JP2021033304
Kind Code:
A
Abstract:
To provide an optical phased array including a member for correcting a phase error generated in a manufacturing process and a method of correcting a phase using the same.SOLUTION: Provided is an optical phased array including a member for correcting a phase error generated in a manufacturing process, and a method of correcting a phase using the same. The OPA (optical phased array) includes a light injector, a first splitter connected to the light injector, a first phase shifter connected to the first splitter, a plurality of waveguides connected to the first splitter, portions of the plurality of waveguides being connected to the first splitter via the first phase shifter, an antenna array connected to the plurality of waveguides, a single mode filter provided in each of the plurality of waveguides, and a first photodetector connected to the first splitter and configured to detect a portion of light radiated onto the antenna array.SELECTED DRAWING: Figure 1
