    (a) Schematic of the two-section GL laser (framed by black dotted square). Evolution of the material gain with the carrier density in both sections (left). Ga,b′ are the differential gains in each section. (b) Schematic of the OIL configuration.
    MTF of the free-running laser without GL calculated from 5 for ϵ=0,5×10−17,10−16,and 5×10−16 cm3.
    MTF of the OIGL laser calculated from 3 for different values of gain compression ϵ=0,10−17,5×10−17,and 10−16 cm3 and with a GL of g=10. The injected power and frequency detuning are (a) K=3.5,Δf/fR=0.97 and (b) K=8,Δf/fR=3.3. Red dotted curves represent the MTF for the free-running case assuming no compression and without GL.
    3 dB bandwidth in the stable-locking region of the OIGL laser with g=10 and ϵ=10−16 cm3.
    Evolution of the 3 dB bandwidth with respect to GL strength and gain compression factor for (a) K=0 and (b) K=8.
