In an optical, e.g. soliton, pulse transmitter the pulse source, e.g. a solid state laser (11), is coupled to means for generating a series of time delayed pulses for each successive generated pulse. The delayed pulses which may be produced by multiple reflection of the laser signal between a pair of parallel plane mirrors (14, 15), are then combined (16) with the original pulse train. This generates a high bit rate pulse stream that may be modulated (15, 18) e.g. by omitting selected pulses, to transmit information. <IMAGE> |
