Abstract
A vertical cavity surface emitting laser (VCSEL)-based free space active optical transceiver component includes a transmitter and a receiver. The transmitter includes first VCSELs, at least one first photodiode, a first focusing lens array or optical system (14), and a first printed circuit board. The receiver includes second photodiodes, at least one second VCSEL, a second focusing lens array or optical system, and a second printed circuit board. 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.
