【Abstract】 The experiment of wavelength conversion using tunable external\|cavity semiconductor laser is performed. The static wavelength conversion is achieved in the tunable wavelength range of the external\|cavity laser. The dynamic wavelength conversions of 155 Mb/s and 622Mb/s NRZ signals are realized respectively. The noise transfer characteristics are studied for laser wavelength converter. The converter has a threshold property in its in\|out relation, which can suppress the “1” noise in the input signal. The improvement of the converted signal has a relationship with the input signal power and ASE bandwidth.更多还原
