In this paper, spatial light modulation is proposed to increase the transmission capacity of graded-index multimode fibers. In the method, selected linearly polarized eigenmodes of the fiber are… (More)
In the paper, an experimental comparison of pulse amplitude, carrierless amplitude-phase, and discrete multitone modulations is carried in a visible light communications link employing white… (More)
We propose spatial light modulation with binary phase filters to increase the transmission bandwidth of multimode fibers. In the experiment more than 300 % of bandwidth enhancement is obtained.
In this letter, the experimental operation of a wireless transmission link employing identical LEDs both as transmitter and receiver is demonstrated. The transmitted signal is a simple, two-level… (More)
In this paper, operation of a cost-effective mode group diversity multiplexing system allowing 3 channel operation is demonstrated. Two different multiplexing/demultiplexing techniques are presented.
Frequency response of Multimode (MM) fibers beyond the baseband is studied both theoretically and experimentally. It is shown that in the absence of mode group mixing there are relative flat… (More)
Optical beat interference is one of the major problems impairing upstream transmission in passive optical networks. In this letter, a theoretical study indicates that if single mode fibers are… (More)
We present a successful transmission of an IEEE 802.11n 2×2 Multiple Input - Multiple Output radio signal over standard graded index multimode fiber at several kilometers length. For the first time… (More)
Fluctuations of the multimode fiber (MMF) frequency response beyond the baseband are observed experimentally when highly coherent light sources are used. This behavior is caused by the variation of… (More)
Employment of MM PON appears to be natural for short-range application such as intra-office or home networks. We have presented the results of the measurements of MM fiber PONs frequency responses in… (More)
