Paper Abstract

Birefringence in multiple quantum well (MQW) layers is utilized in a novel way to realize high performance two-dimensional spatial light modulators (SLMs). The polarized light is coupled into MQW layers using a grating. The light is modulated by an externally applied electric field which changes the birefringence in each pixel. The modulated light is recovered using a turning mirror similar to those employed in surface-emitting laser configurations. The usage of birefringence is shown to result in significantly higher contrast ratios than obtained in devices (e.g., SEEDs) using only electroabsorption. Both electrically and optically addressed structures are described.
