Abstract

Micro-resonator modulators exploiting the quantum confined Stark shift and incorporating the asymmetric Fabry-Perot have been fabricated which exhibit high contrast (15 - 20 dB), and large reflectivity changes (> 50%) at low voltages (3V - 4V). This paper will review progress made in the development of these devices and will consider how the performance can be modified, post growth, by use of intermixing techniques to modify the shape of the quantum wells. The asymmetric Fabry Perot structure is also a convenient configuration to investigate the intermixing process itself. Measurement of the lateral extent of the intermixing process promoted by vacancies in GaAs/AlGaAs structures obtained using this structure are reported.
