(research project with J. Vuckovic Group at Stanford)

The Idea:

• Create advanced single photon sources for quantum communication and computation, using QDs coupled to photonic crystal cavities.

Reasons:

• on-demand efficient single photon source
• controlled spontaneous emission lifetime
• high spontaneous emission coupling efficiency into cavity mode
• improved indistinguishability
• improved off-chip coupling efficiency
• spin-offs: improved LEDs

Materials:

• Self-assembled InAs QDs embedded in GaAs
• wafers grown by Molecular Beam Epitaxy (collaboration with Y. Yamamoto group (Stanford) and P. Petroff Group (UCSB)
• Photonic crystal fabrication: Vuckovic group
