Ultra high speed network using optical solitons

--Generation and Transmission of Pico-second optical solitons--

• Pico-second soliton generation by use of induced modulational instability

  We generate ultra-short optical pulse with a few pico-second pulse width and repetition rate more than 100 GHz by use of induced modulational instability. Optical beat signal obtained from two LD's with slightly different wavelength is launched into the properly designed optical fiber, where the signal is compressed by balancing frequency chirp induced by both fiber dispersion and nonlinearity.
