Abstract
We analyse the effects of optical feedback in a laser diode in the frequency of emission and optical output power. We observe experimentally that the dynamics properties of injection laser are affected by the interference between light of the laser diode cavity and backscattered light. We demonstrate that the light intensity shows hysteresis and discrete shifts of frequency according to feedback light and/or forward current variations condition due at non-linear active layer.
