ABSTRACT
An exact analysis of the excess noise in a two-mirror laser that takes into account the intracavity elements and the position of the active medium is presented. The influence of the active medium's position and length of the laser cavity on the excess noise factor is shown.
ABSTRACT
An analysis of the quantum noise in distributed-feedback lasers based on the Fokker-Planck equation has been developed to take into account the nonorthogonal nature of the laser modes. We have obtained numerical results of the steady-state solution of the single-mode operation that reveal the difference between the standard approach orthogonal laser modes and the realistic model (mode nonorthogonality included) for a distributed-feedback laser with nonvanishing end reflectivity and the complex coupling coefficient.
