  • Simulation of electro-optic effects in III-V semiconductor structures.

    • Main Results:

    • A phase modulation of 0.7pi radians was achieved with 90% reflecting electrodes.
    • This modulation occurred for an electro-optic input phase of 0.06pi radians.
    • The analysis confirmed significant phase enhancement through resonant effects.

    Conclusions:

    • Resonant Fabry-Perot elements can significantly enhance phase modulation in III-V semiconductor SLMs.
    • Implementation in AlGaAs/GaAs multiple quantum well structures is feasible.
    • Field and carrier-induced electro-optic effects are key mechanisms for MQW SLMs.
