High speed electro-absorption modulator for long range retroreflective free space optics

In this work we present the design and implementation of a pixelated electro-absorption modulator (EAM) based modulating retroreflector (MRR) for high speed optical wireless communications. The modulator is based on a multiple quantum well (MQW) structure embedded in an asymmetric Fabry-Perot (FP) c...

الملخص:In this work we present the design and implementation of a pixelated electro-absorption modulator (EAM) based modulating retroreflector (MRR) for high speed optical wireless communications. The modulator is based on a multiple quantum well (MQW) structure embedded in an asymmetric Fabry-Perot (FP) cavity. This MRR was used in an outdoor link, operating at 150 Mbps with a bit error rate (BER) of 1.22 x 10-6 at a range of 200 m. The system was also tested in laboratory controlled conditions achieving a data rate of 200 Mbps with a BER of 2 x 10-4. To the best of our knowledge, this is the fastest retroreflective free space optics (RFSO) demonstration in both indoor and outdoor environments.
