Abstract
This article deals with research of luminous sources which could be applied in indoor Free Space Optic (FSO) networks. Indoor FSO networks have potential to replace standard IEEE 802.11 in the future. Suitable selection and configuration of optical radiation sources can at the same time provide communication and lighting in indoor spaces. This article is engaged in spectral mergence of optical sources, willful suppression of part of emitted visible spectrum and consequential restoration of this optical spectrum.
Highlights
The users of data networks have two main requirements, high data rate and mobility
This article describes the suppression of part of the spectrum emitted by a white power LED diode and the restoration of the suppressed spectrum
LED diode and the laser diode had to be changed according to the real measurements in the laboratory
Summary
The users of data networks have two main requirements, high data rate and mobility. In indoor spaces the standard IEEE 802.11, known as Wi-Fi, fulfills these requirements. The indoor FSO networks use a visible light for communication, most often white LED diodes. For illumination the white power LED diode Luxeon The spectral characteristic of this power LED diode was measured in a laboratory by spectrometer USB650 by the Ocean Optics Company.
