<p>A communications system is characterized by a pulse-shaping technique for producing shaped, stabilized, ultra-short (picosecond to femtosecond) pulses containing encoded information. Pulse shaping is accomplished by temporally stretching (3) and chirping an ultra-short pulse (2) from a pulse generator (1), modulating (5) the pulse (4) in real time and temporally compressing (11) the pulse in a manner so as to cancel the original chirp.</p> |
