Abstract

The spectral flatness of multiwavelength emission from an InGaAsP semiconductor optical amplifier based ring laser is controlled by a programmable liquid crystal spatial light modulator based on spectrally monitoring the individual wavelength intensities of the laser output. Spectrally equal amplified output is also shown by predistorting the laser to account for amplifier spectral gain dependence
