Paper Abstract

Collimation is important for long-range transmission in a Wireless Optical Communication (WOC) system. We developed a novel method to control the size of lens used in collimation of VCSEL based WOC systems. In our design example, the divergence angle is well-controlled to be 0.106 mrad achieved by two lenses with each focal length > 60mm and the system total length < 80 mm. Also, we proposed a universal framework based on light field representation for modeling similar optical systems.
