“…Initially only light emitting diode (LED) based systems with data rates in the lower Mbit/s range [2,3] or laser diode based uni-directional links were demonstrated [21]. Faulwaßer et al [19] introduced a full-duplex link for data rates of up to 10 Gbit/s for on-axis rotary data transfer. Similar to fiber-based communications, data rates are likely to increase in the future.…”

“…The optoelectronic components, i.e., light emitting diodes (LEDs), laser diodes (LDs) and photodiodes (PDs) are known for high reliability and long lifetime [22][23][24]. The key element of the transceiver in [19] is a monolithic hybrid lens that acts as transmitter (TX) and receiver (RX) optics in parallel and thereby relaxes the mechanical alignment to several millimeters. The form factor of the transceiver is only 5 mm × 5 mm × 5 mm [19].…”

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 .

This work experimentally demonstrates for the first time the practical feasibility of a freeform multipath lens (MPL) for optical wireless communications (OWC). The MPL is able to increase the eye safety laser power limit. Our transmitter is laser class 1M and features 190 mW optical output. We transmit 1.289 Gbit/s on-off keying (OOK) data and achieve a bit error ratio (BER) of 10 −10 for an optical receiver power of −31.2 dBm. The link range is more than 5 m, depending on the targeted BER. We discuss the pros and cons of MPLs and compare them with diffusers.

Total Internal Reflection Lens for Optical Wireless Receivers

et al. 2022

This work considers the use of a freeform total internal reflection (TIR) lens for optical concentration and provides for the first time experimental results in the context of optical wireless communications (OWC). The lens is placed on a surface-mounted device (SMD) avalanche photodiode (APD) to minimize position tolerances and simplify assembly. The lens achieves a concentration ratio of go = 44.7 (16.5 dB) within the FOV center and exhibits an acceptance angle of ±5°. The TIR lens approach is validated by comparing eye diagrams and bit error ratios (BER) of a receiver with and without a TIR lens. For the measurements, non-return-to-zero (NRZ) on-off keying (OOK) signals are transmitted with a data rate of 1.289 Gbit/s.
