Control of surfacehyphen;emitting laser diodes by modulating the distributed Bragg mirror reflectivity: Smallhyphen;signal analysis

摘要

Cavityhyphen;loss control of surface emitting distributed Bragg reflector lasers by electrohyphen;optic modulation of the Bragg mirror reflectivity is shown to be more efficient at high frequencies than the conventional control by current modulation. Combining both means of control offers additional possibilities, such as the elimination of relaxation oscillations and the achievement of a pure frequencyhyphen;modulation regime.
