Embodiment Construction

[0049] Hereinafter, an optical component according to an embodiment of the present invention will be described. The optical component is an optical component including a swirl shape. The same or equivalent components, members, and processes shown in the drawings are assigned the same reference numerals, and redundant descriptions are appropriately omitted. In addition, the embodiment does not limit the invention, but is only an example, and not all features and combinations described in the embodiment are the substantive content of the invention.

[0050] figure 1 It is a schematic cross-sectional view for describing the optical component 10 according to the embodiment of the present invention. Such as figure 1 As shown, the optical component 10 is an optical component in which a first layer 12 and a second layer 14 are laminated. The first layer 12 is composed of a first refractive index n 1 The 1st material is formed. The second layer 14 is formed by having the second ...

Abstract

An optical component 10 is provided with: a first layer 12, which is formed of a first material having a first refractive index, and which has a first main surface 16 and a second main surface 18 on the reverse side of the first main surface 16; and a second layer 14, which is formed of a second material having a second refractive index different from the first refractive index, and which has a third main surface 20 and a fourth main surface 22 on the reverse side of the third main surface 20. The first layer 12 and the second layer 14 are laminated to each other such that the second main surface 18 and the third main surface 20 are in contact with each other. A lens 24 is formed on the first main surface 16 of the first layer 12, and a vortex shape 26 is formed on the third main surface 20 of the second layer 14.

Description

technical field [0001] The present invention relates to an optical component and a method of manufacturing the same. Background technique [0002] In recent years, due to the popularization of the Internet and the cloud, the amount of data communication is growing explosively. Even in data centers that temporarily store data or connect to the Internet, large volumes of data need to be exchanged at high speed. [0003] Although communication by electrical signals is performed for short-distance (tens of meters to hundreds of meters) transmission as in a data center, optical communication is advantageous in terms of speeding up. In short-distance optical communication, a system combining VCSEL (Vertical Cavity Surface Emitting LASER: Vertical Cavity Surface Emitting Laser) isosurface-emitting light source and multimode optical fiber with a transmission speed of several GHz to 10 GHz has been realized. [0004] Compared with single-mode fiber, the core through which light pas...
