Abstract
A short-waveband active optical component based on a vertical emitting laser and a multi-mode optical fiber (3) is provided. In the component, multiple VCSELs (11) are configured to be used for generating multiple optical signals of different wavelengths; multiple photodiodes (15) are configured to be used for receiving the optical signals emitted by the VCSELs (11); two focusing lens arrays (12, 22) or lens array group elements are configured to be used for collimating and focusing optical signals at an emitting end (1) and a receiving end (2); two Z-block-shaped prisms (13, 23) are configured to be used for a light combining function of the emitting end (1) of the optical component and a light splitting function of the receiving end (2); one multi-mode optical fiber (3) is configured to be used for transmitting the optical signals generated by the VCSELs (11); and two focusing lenses (14, 24) are configured to be used for collimating and focusing optical signals at two ends of the multi-mode optical fiber (3). The short-waveband active optical component has a small size and a high transmission rate.
