    Abstract: A two-way optical path system includes a metasurface lens. The metasurface lens is configured to deflect first incident light incident on a first surface of the metasurface lens as first outgoing light and second incident light incident on a second surface of the metasurface lens as second outgoing light. The first outgoing light and the second outgoing light are received by a first image sensor and a second image sensor for imaging, respectively, or the first incident light and the second incident light are from a first light emitter and a second light emitter, respectively.

    Abstract: A spectrometer includes a collimator, a grating array, a metasurface, and a photodetector. The collimator is configured to collimate light including a plurality of portions with different wavelengths. The grating array is configured to guide, disperse, and deflect the light from the collimator. The metasurface array is configured to guide and focus the light from the grating array. The plurality of portions of the light with different wavelengths are focused by the metasurface array to different positions on a detection plane. The photodetector is configured to receive the light from the metasurface array at the detection plane.

    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.
