| Abstract;Nonlinearity of distributed feedback(DFB) lasers has been investigated. Nonlinear property of the laser is essentially originated form three factors: 1) longitudinal spatial hole burning(LSHB), 2) leakage current, and 3) intrinsic nonlinear response. This paper provides several approaches to improve the linearity by examining these factors theoretically and experimentally. In addition, noise characteristics related to laser property after fiber transmission is also discussed. These studies significantly develop DFB lasers for analog optical communication.
