Abstract
Amplification of optical signals propagating through a first waveguide is achieved by modulation of high intensity light propagating through an elastomeric waveguide responsive to said signals, the modulation of the high intensity light being accomplished by an apparatus including a photodiode for registering the modulation of the optical signals and an electrode arrangement for causing corresponding light-modulating deformation of the elastomeric waveguide, the circuitry between photodiode and the electrode arrangement including a resistor and a D.C. power source.
