| Abstract: | The electrical noise in semiconductor lasers depends not only on the optical intensity noise behavior but also on device quality. Several important laser parameters and characteristics can be extracted from electrical noise measurement. Among these are the relaxation frequency, the threshold current, the emission linewidth, optical feedback properties, and mode hopping behavior, etc. On the other hand, the electrical noise can also be used to estimate the device reliability, which is a fast and nondestructive method. In this paper, a review of recent development on electrical noise in semiconductor lasers and its applications is presented. |
