摘要： A vertical cavity surface emitting laser (VCSEL)-based free space active optical transceiver component is provided, which includes: a transmitter that includes a plurality of VCSELs (12), at least one photodiode (13), a first focusing lens array (14) or a first optical system (14), and a first printed circuit board (11); and a receiver that includes a plurality of photodiodes (22), at least one VCSEL (23), a second focusing lens array (24) or a second optical system (25), and a second printed circuit board (21). The transmission and reception of a short/medium-distance free space (wireless) high-speed optical communication signal can be implemented, and a single-channel transceiving rate may reach 10 Gbps or higher. The component may be used for implementing a free space high-speed signal transmission function in a short/medium-range high-definition multimedia interface (HDMI) device. In addition, the component also has the characteristics of free space connection, high transmission rate, low cost, small size, easy assembly and mass production, etc., and has a broad market prospect.

摘要： A short-waveband active optical component based on a vertical emitting laser and a multi-mode optical fiber has an emitting end and a receiving end. In the emitting end, multiple VCSELs generate multiple optical signals of different wavelengths, and multiple photodiodes in the receiving end receive the optical signals emitted by the VCSELs. Both ends use a focusing lens array to collimate and focus the optical signals A Z-block-shaped prism performs a light combining function at the emitting end, while another Z-block-shaped prism performs a light splitting function at the receiving end. Both ends use a focusing lens for collimating and focusing the optical signals at ends of a multi-mode optical fiber, which is used for transmitting the optical signals generated by the VCSELs. The short-waveband active optical component has a small size and a high transmission rate.
