Abstract :
A theory is given for the frequency noise of saturated laser diodes having arbitrary geometry. The frequency noise is expressed in terms of integrals of the unperturbed resonating field. The formula simplifies considerably when the shot noise contribution, in addition to the spontaneous emission contribution, is taken into account. The validity of the perturbation formula used is verified by comparison with a direct exact calculation for a two-active-element electrical circuit
