“…These different effects can be divided into two regimes of feedback as shown in Fig. 2 for a typical 850-nm GaAs laser [2], [12] reflectivity of back facet 0.6 -below 500MHz which corresponds to the quantum noise; and shows a broad peak near 3GHz which corresponds to the relaxation oscillation frequency. The RIN in lower frequency region of the spectrum (<20MHz) appeared to be enhanced by a large amount (>20dB) when the optical feedback ratio Г was increased from 0 to 2.45x10 -3 .…”

“…The RIN in lower frequency region of the spectrum (<20MHz) appeared to be enhanced by a large amount (>20dB) when the optical feedback ratio Г was increased from 0 to 2.45x10 -3 . This RIN enhancement is due to unstable mode hopping between two lasing modes [12]. We call here this type of noise to be low frequency type noise.…”
