2D HETEROSTRUCTURES FOR INTEGRATED ON-DEMAND SINGLE-PHOTON SOURCES
Abstract
We intend to develop novel single-photon sources based on stacks of monolayers of different materials, which will then be transferred to waveguides and other photonic structures. By assembling stacks of different types of 2D materials (heterostructures) it is possible for instance to protect a 2D semiconductor from external spurious effects using a 2D insulator such as hexagonal BN, and to use graphene gates to pump the emitter or tune the energy of the emitted photon. Our photonic structures will be fabricated from a SiN3 layer grown on top of a silica-on-silicon wafer, all CMOS compatible materials, with protrusions designed to induce the highly localized stress necessary for obtaining single-photon emission at pre-determined positions in 2D semiconductors. We expect to obtain single-photon sources that operate on demand by an electrical signal, and that can be easily integrated into more complex photonic circuits, in order to perform quantum information tasks or to act as nodes in quantum information networks.
