A simple model is presented for the frequency deviation or chirp caused by modulation-induced variations in the carrier density in the active region of a semiconductor laser. Predictions from this model are compared with experimental measurements of sinusoidal frequency modulation in the range 0.8 to 3.0 GHz and show good agreement
