Abstract

We propose and demonstrate a novel bi-directional free-space (FS) optical wireless communication system for indoor wireless networks. A 2-D infrared beam-steered system supporting full-duplex communication of at least 10 Gb/s capacity per wireless terminal with simple NRZ-OOK modulation format is experimentally demonstrated. The uplink (UL) is implemented using the optical carrier recovery technique, in which the downlink (DL) OOK modulation is erased by means of two cascaded SOAs operating in the saturation region. We experimentally demonstrate the system with asymmetric speeds (10 Gb/s DL/2.5 Gb/s UL) and symmetric speeds (10 Gb/s) duplex communication over an FS transmission distance of 3 m. We also report the crosstalk in such a system.
