Dynamical effects in semiconductor lasers due to optical feedback

الملخص EN

Semiconductor lasers subjected to accidental or intentional feedback are prone to instabilities.

Operating conditions for long external cavity laser diodes which resulted in various instabilities were determined and plotted on a current versus feedback ratio graph.

For most applications, it is essential that the lasers be operated under conditions which avoid accidental instability behavior, and the graphs produced identify the stable operating conditions for laser diodes.
