Abstract
This work theoretically investigates the influence of intensity and frequency noise on the locking range of a semi-conductor laser. The analysis was conducted using the numerical simulations based on the developed locking range model including the noise sources. The effect of intensity noise resulted in a broadening of the locking range by shifting its lower boundary along the detuning frequency axis and the effect of frequency noise has shifted the locking range without changing the locking range width. When intensity and frequency noise are considered simultaneously, the locking range shows a superposition of the individual variation of each type of noise. The results obtained through this work is applicable only for the lower injection ratio applications such as optical sensors.
