Abstract
A transmitter for fiber optics communication having a solid state light source device biased to emit light and a solid state optical amplifier device positioned adjacent the source device to receive the emitted light and amplify it. A modulation current is provided to one of the devices so as to cause a corresponding modulation of the output light from the optical amplifier, for transmission of the information contained in the modulation. The invention is advantageous for multiple state digital encoding. In addition, it can generate a multiplexed output, which facilitates demultiplexing of the information transmitted.
