Monolitic Hybrid Transmitter-Receiver Lens for Rotary On-Axis Communications

Abstract

High-speed rotary communication links exhibit high complexity and require challenging assembly tolerances. This article investigates the use of optical wireless communications (OWC) for on-axis rotary communication scenarios. First, OWC is compared with other state-of-the-art technologies. Different realization approaches for bidirectional, full-duplex links are discussed. For the most promising approach, a monolithic hybrid transmitter-receiver lens is designed by ray mapping methodology. Ray tracing simulations are used to study the alignment-depended receiver power level and to determine the effect of optical crosstalk. Over a distance of 12.5 m m , the lens achieves an optical power level at the receiver of − 16.2 dBm to − 8.7 dBm even for misalignments up to 3 m m .

“…The category of optical communications is represented by a research article from Kirrbach et al [6] and a review article from Lallas [7]. The research article from Kirrbach et al [6] investigates the use of Optical Wireless Communications (OWC) for on-axis rotary communication scenarios by discussing different realization approaches for bidirectional full-duplex links as well as designing a monolithic hybrid transmitter-receiver lens and studying its performance using ray trancing simulations. The article by Lallas [7] reviews current and future state-of-the-art plasmonic system implementations for THz communications.…”
