PHASE LOCK AND STATIONARY FLUCTUATIONS INDUCED BY CORRELATION BETWEEN ADDITIVE AND MULTIPLICATIVE NOISE TERMS IN A SINGLE-MODE LASER

摘要

According to a two-dimensional model stochastically equivalent to the single-mode cubic laser model with correlation between additive and multiplicative noise terms, it is found that a stable lock of laser phase will occur when the multiplicative noise has some forms of correlation with additive noise. A reduction of the fluctuation in phase is obtained consequently. The stationary fluctuation in the laser intensity increases when the two noises are positively correlated, and decreases when negatively correlated. (C) 1997 Published by Elsevier Science B.V.
