Optical alignment device and optical alignment method

An optical alignment device comprising:

• an input optical fiber;
• a light source provided at one terminal of the input optical fiber and configured to generate input light;
• an input stage provided at another terminal of the input optical fiber and provided adjacent to one side of a waveguide chip;
• an output stage provided adjacent to another side of the waveguide chip and spaced apart from the input stage;
• a stage driving control unit connected to the input and output stages and configured to control driving of the input and output stages;
• a camera mounted on the output stage, and configured to receive output light generated from the input light by the waveguide chip and detect a waveguide mode;
• an output optical fiber provided adjacent to the camera, and having one terminal connected to the output stage;
• an optical power meter connected to another terminal of the output optical fiber and configured to receive the output light to detect an intensity of the output light;
• a system controller connected to the optical power meter, the camera, and the stage driving control unit, and configured to determine the waveguide mode and the intensity of the output light;
• and
• a six polarization modes generation unit between the input optical fiber and the waveguide chip.
