Electrooptic fabry-perot pixels for phase-dominant spatial light modulators

摘要

Phase enhancement by resonant Fabry-Perot picture elements in III-V semiconductor spatial light modulators (SLMs) is disclosed. For 95% reflecting electrodes, a phase modulation of 0.7&pgr; rad is found in transmission when the electrooptic input phase is 0.06&pgr; rad. A resonant phase-dominant SLM in a 1.7-&mgr;m-thick AlGaAs/GaAs multiple quantum well (MQW) structure can employ field effects and carrier-induced electrooptic effects within the MQWs.
