The relative-intensity noise (RIN) is an important quantity in determining whether lasers are acceptable for use in optical-commu nication systems. Its analytic study can require extensive algebra, but in this appendix the emphasis is on the physical significance of RIN and simulations using time-domain modelling to estimate its value for DFB lasers.
