A variable pulse width optical pulse generation system includes a first and a second optical interferometric modulator. A first drive signal applied to the first modulator modulates an input optical signal, so as to provide a first modulated optical signal. A second drive signal applied to the second...http://www.google.de/patents/US20020141027?utm_source=gb-gplus-sharePatent US20020141027 - Variable pulse width optical pulse generation with superposed multiple frequency drive
