Abstract
The invention is directed to an optical transmission system employing an electro-absorption modulator operative that absorbs energy from light received from a source of light and modulates the received light with information signals received from a source of information and outputs the modulated light signal to an optical transmission line, and employing apparatus that controls the level of light signals provided by the source as a function of a control signal having a level proportional to the level of the absorbed energy.
