    Abstract: An optical communication device includes a plurality of laser sources, a plurality of first meta-lenses, and an optical fiber. The laser sources transmit a plurality of laser beams in the same direction according to electrical signals. The laser beams have different wavelengths. The first meta-lenses receive the laser beams, and in a first substrate, refract the laser beams to a focal point to generate a mixed laser beam. The optical fiber receives the mixed laser beam for transmission. The focal point is arranged at the input end of the optical fiber.
