Abstract
Visible light communications (VLC) is one of the upcoming technology, which utilizes light emitting diodes (LEDs) or organic LEDs (OLEDs) to provide a combination of illumination and data communications. OLEDs have been gaining attention within the VLC research community due to their inherent advantages such as low-cost manufacturing and flexible substrates, which allows having a curved, rolled or folded lighting. This paper presents the impact of a symmetry beam pattern of OLED, which is wider than Lambertian, on the VLC system by considering wavelength-dependent surface materials reflections. A VLC system using flat and half-circular flexible OLEDs for use in an office environment for a number of scenarios is simulated. We obtain channel impulse responses and present the channel DC gain and optical path loss. The system performance is investigated in terms of the bit error rate and the channel capacity.
