Definition
The concept of light tree is introduced in a wavelength routed optical network, which employs wavelength -division multiplexing (WDM).
Depending on the underlying physical topology networks can be classified into three generations:

a).First Generation: these networks do not employ fiber optic technology; instead they employ copper-based or microwave technology. E.g. Ethernet.
b).Second Generation: these networks use optical fibers for data transmission but switching is performed in electronic domain. E.g. FDDI.
c).Third Genera ....etc

ABSTRACT
The concept of a light-tree is introduced in a wavelength-routed optical network. A light-tree is a point-to-multipoint generalization of a lightpath. A lightpath is a point-to-point all-optical wavelength channel connecting a transmitter at a source node to a receiver at a destination node. Lightpath communication can significantly reduce the number of hops (or lightpaths) a packet has to traverse; and this reduction can, in turn, significantly improve the networkâ„¢s ....etc

Abstract:
electrodeless lamp is a light source in which the power required to generate light is transferred from the outside of the lamp envelope by means of (electro)magnetic fields.Two systems available noe—one, plasma lamps, based on the use of radio waves energizing a bulb filled with sulfur or metal halides, and the other is, fluorescent induction lamps, based upon conventional fluorescent lamp phosphors .. and the Magnetic induction lamps are basically fluorescent lamps with electromagnets wrapped around a part of the tube, or ....etc
