VCSEL-Based Free Space Active Optical Transceiver Component

Abstract

A VCSEL-based free-space active optical transceiver module comprises a transmitting end including 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 receiving end including a plurality of photodiodes (22), at least one VCSEL (23), a second focusing lens array (24) or a second optical system (14), and a second printed circuit board (21), and can realize the transmission and reception of short-range and medium-range free-space (wireless) high-speed optical communication signals, and can achieve a single channel transmission and reception speed of 10 Gbps or more. This can be used to realize free-space high-speed signal transmission functions in short-range and medium-range High Definition Multimedia Interface (HDMI) devices, and has wide marketability by having features such as free-space connectivity, high transmission speed, low cost, small area, ease of assembly, and mass production.
