Making Hydrogen Fuel Water Visible Light Highly Efficient
2015/9/9
Mimicking photosynthesis is not easy. The bottleneck of artificial photosynthesis is visible light, because converting it into other forms of energy is not efficient. Researchers at Michigan Technolog...
803 Mbit/s Visible Light WDM Link based on DMT Modulation of a Single RGB LED Luminary
Free-space optical communication Light-emitting diodes
2015/5/25
We report the first visible light link based on WDM and DMT modulation of a single RGB-type white LED, operating at an aggregate rate of 803 Mbit/s within the FEC 2·10 -3 limit.
Equalization and Pre-distorted Schemes for Increasing Data Rate in In-door Visible Light Communication System
Equalization Pre-distorted Increasing Data Rate Visible Light Communication System
2015/5/18
We propose and demonstrate using signal pre-distortion and equalization schemes for increasing the data rate of the white-light LED communication system. Bit-error-rate of <10 -10 at 10-Mb/s operation...
A High-Speed Visible Light Indoor Network Employing a Short Pulse Modulation and a QPM-LN Module
High-Speed Visible Light Indoor Network Short Pulse Modulation QPM-LN Module
2015/5/18
We propose the concept of over-gigabit visible light indoor networks using λ-conversion achieved by combining a short pulse modulator with a QPM-LN module. Error free operation at 1.25 Gb/s is confirm...
230 Mbit/s via a Wireless Visible-Light Link based on OOK Modulation of Phosphorescent White LEDs
Free-space optical communication Light-emitting diodes
2015/6/8
We report a first indoor wireless visible-light link operating up to 230 Mbit/s by use of on-off-keying and with bit-error-ratios below 2·10 -3 . The results were achieved for illuminance levels recom...
This article introduces "visible light communication" using visible light sources as transmitters and discusses its applications and standardization activities.
80 Mbit/s Visible Light Communications Using Pre-Equalized White LED
Visible Light Communications Pre-Equalized White LED
2015/8/6
This paper reports an 80 Mbit/s OOK-NRZ Visible Light Communications experimental link using a single pre-equalized 45-MHz bandwidth white LED.
Fluorescence detection of biological objects with ultraviolet and visible light-emitting diodes
semiconductor light emitting diodes (LEDs) UV LEDs fluorescence lifetime
2011/4/28
Recent progress in fabrication of semiconductor light emitting diodes (LEDs) allows these devices to be used for excitation of fluorescence of aromatic amino acids and other biofluorophores. In our wo...
