Abstract
In a system for transmitting intensity modulated light waves ( ) over an optical fiber ( ), an optical data transmission apparatus ( ) includes a cw laser ( ) conformed to emit light at substantially a single frequency. A phase modulator ( ) is connected in series with the cw laser ( ), wherein the phase modulator ( ) is conformed to cause the light from the cw laser ( ) to vary in substantially a quadratic manner as a function of time during a time interval T. An intensity modulator ( ) is connected in series with the phase modulator ( ), wherein the intensity modulator ( ) is conformed to transmit or block the light from the phase modulator ( ) in accordance with an intensity modulation scheme for transmitting binary data, such that the transmitted light consists of pulses ( ) of temporal width T during which the phase of the light varies in substantially a quadratic manner as a function of time.
