VCSEL-based free-space active optical transceiver module

摘要

A VCSEL-based free-space active optical transceiver module 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 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 . It includes a receiving end, which can realize short-distance and medium-distance free space (wireless) high-speed optical communication signal transmission and reception, and a single-channel transmission/reception speed of 10 Gbps or more. It can be used to realize high-speed signal transmission in free space in short-range and medium-distance high-definition multimedia interface (HDMI) devices, and features such as free-space connection, high transmission speed, low cost, small area, ease of assembly and mass production. It has a wide market potential.
