Visible light communication (VLC) is an optical wireless communication\ntechnology that is considered a promising solution for high-speed indoor\nconnectivity. Unlike the case in conventional radio-frequency wireless systems,\nthe VLC channel is not isotropic, meaning that the device orientation affects\nthe channel gain significantly. In addition, due to the use of optical\nfrequency bands, the presence of different obstacles (e.g., walls, human\nbodies, furniture) may easily block the VLC links. One solution to overcome\nthese issues is the integration of the intelligent reflective surface (IRS),\nwhich is a new and revolutionizing technology that has the potential to\nsignificantly improve the performance of wireless networks. IRS is capable of\nsmartly reconfiguring the wireless propagation environment with the use of\nmassive low-cost passive reflecting elements integrated on a planar surface. In\nthis paper, a framework for integrating IRS in indoor VLC systems is presented.\nWe give an overview of IRS, including its advantages, different types and main\napplications in VLC systems, where we demonstrate the potential of IRS in\novercoming the effects of random device orientation and links blockages. We\ndiscuss key factors pertaining to the design and integration of IRS in VLC\nsystems, namely, the deployment of IRSs, the channel state information\nacquisition, the optimization of IRS configuration and the real-time IRS\ncontrol. We also lay out a number of promising research directions that center\naround the integration of IRS in indoor VLC systems.\n
