Optical Feedback In Semiconductor Lasers

The current book is a review of author research about nonlinear dynamics in optically injected semiconductor laser. a) A new method is introduced to measure the thickness and refractive index of transparent thin films by Self-mixing interferometry which is an important application of weak optical feedback in semiconductor lasers. b) The regimes of perturbation in a laser diode subjected to delayed optical feedback (DOF) from an external reflector is numerically analyzed from short to long cavity and from weak to strong optical feedback.
