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.

An optical communication device, comprising:
- a plurality of laser sources, transmitting a plurality of laser beams in the same direction according to electrical signals;
- wherein the laser beams have different wavelengths;
- a plurality of first meta-lenses, receiving the laser beams, and in a first substrate, refracting the laser beams to a focal point to generate a mixed laser beam;
- an optical fiber, receiving the mixed laser beam for transmission;
- wherein the focal point is arranged at the input end of the optical fiber,
- wherein each of the first meta-lenses is designed individually, so that the refraction angles of the laser beams passing through the first meta-lenses will match the numerical aperture (NA) of the optical fiber.
