Abstract: An endoscopic probe is provided, and the endoscopic probe includes: an optic fiber and a metalens. The optic fiber includes: a signal input fiber core, a signal output fiber core and a coating; the signal input fiber core is used to transport an input laser signal. The metalens includes: a translucent substrate, a plurality of nanostructures arranged on the one side of the surface of the substrate. The plurality of nanostructures are arranged in array and attached to a distal surface of the signal input fiber core, so as to focus the input laser signal on an inner surface of tissues to be detected; and the signal output fiber core is used for transporting a laser signal reflected through the inner surface of the tissue to be detected, so as to obtain an image of the inner surface of the tissue to be detected after the reflected laser signal processing.

Abstract: Provided is a metasurface for improving a light extraction efficiency of a light-emitting diode, including a substrate and unit cells. The substrate being transmissive to optical radiation is on a metal oxide layer of the light-emitting diode. The unit cells are on a side of the substrate away from the metal oxide layer and formed in densely-packed patterns. A center and/or a vertex of each densely-packed pattern are respectively provided with a nanostructure. Nanostructures are divided into four quadrants by a first axis and a second axis. A projection of a cross-sectional quadrant pattern in any quadrant onto the first axis is the same as that onto the second axis. The cross-sectional quadrant pattern in any quadrant is mirrored along the two axes to form a cross-sectional pattern of the nanostructures. The first axis, the second axis and a height direction of the nanostructures are perpendicular to each other.
