In this paper, analysis of a dual-band filter using hairpin resonator is presented. By geometrical modifications of a hairpin resonator, bands stop and band pass characteristics are observed in the frequency spectrum. The variations of the geometrical parameters have been…

In this paper, an experimental demonstration of an indoor optical wireless multiple-input-multiple-output (MIMO) system with a non-imaging receiver is proposed. The system setup consists of a 2×2 array of white light-emitting diodes (LEDs) with spacing 15cm, and a 2×2 photo-detector…

The paper presents development of a 10 Mbit/s visible light communications link that uses lighting LEDs as both transmitters and receivers. The system uses the simple binary on-off keying modulation without any equalization. Transmission distances exceeding 20 cm were obtained…
