An amplifying optical element for use within an optical fiber communication system
is disclosed which includes a doped optical fiber, an optical excitation source
which is physically integrated with and immediately adjacent to and surrounding
doped optical fiber, the excitation source being capable of emitting sufficient
light to enable power gain of the signal being transmitted, and an external power
source electrically connected to the optical excitation source for initiating and
maintaining the light emission. Preferably, the excitation source is a multilayer
electrically conductive structure which includes a first layer immediately adjacent
to the doped optical fiber, wherein the first layer is a transparent, electrically
conductive material, a second layer adjacent to the first layer, wherein the second
layer is an electroluminescing material, and a third layer adjacent to the second
layer, wherein the third layer is an electrically conductive material. Most preferably,
a buffer layer is included between the first and second layer and between the second
and third layer. Alternatively, the excitation source may be a microring laser,
which may be optically excited.
