Device for wavelength conversion of optical signal wavelength into another wavelength, has laser light source, which emits optical signal of wavelength
The device has laser light source, which emits an optical signal (S1) of a wavelength (Lambda1), and another laser light source (L2), which emits another optical signal (S2) of another wavelength (Lambda2). An optical filter (10) is provided for central wavelength of the latter laser light source. The optical semiconductor amplifier (SOA) has a length greater than 1.5 millimeter. An independent claim is included for a method for conversion of amplitude-modulated laser radiation of a wavelength into amplitude-modulated laser radiation of another wavelength.
