Abstract: A collimation fiber adapter includes a base, a metasurface collimation lens, a sleeve, and a fiber ferrule. The base includes a mounting cavity with a positioning structure at an end of the mounting cavity. The metasurface collimation lens is connected to the positioning structure. The sleeve is arranged inside the mounting cavity. An end of the sleeve away from the positioning structure is configured to assemble a fiber. The fiber ferrule is arranged inside the mounting cavity and assembled with an end of the sleeve close to the positioning structure. A first side end surface of the fiber ferrule away from the positioning structure is configured to be coupled with the fiber. A second side end surface of the fiber ferrule close to the positioning structure is opposite to the metasurface collimation lens.
