Abstract: A high speed spatial light modulators are described. In one non-limiting example, an optical phased array structure comprises a vertical cavity surface-emitting laser (VCSEL) that provides a light beam and a phase delay unit that includes a bi-layer photonic crystal slab. The bi-layer photonic crystal slab (PCS) is attached to the VCSEL and comprises two silicon PCS layers separated by a dielectric layer. The optical phased array structure is configured to control a direction of the light beam by a voltage applied to the phase delay unit. By incorporating a dispersive layer (e.g. graphene), the absorption of the structure can be modulated and accordingly the reflection of the surface can be modulated as well.
