ABSTRACT:
An arrangement for operation as an optical feedback amplifier which is composed of a DFB laser whose grating selects a wavelength that differs by so much from the wavelength at which the amplification medium has a maximum gain that a constant amplification effect at this beamed-in wavelength is achieved by a progressive quenching of the emission of this wavelength selected by the grating given external optical irradiation via a coupled waveguide of light having a wavelength in the proximity of the wavelength of the gain maximum of the amplification medium.
