Research activities of the the NanoPhotonics Lab include fabrication and quantum-optical characterization of functional nanostructured devices made from compound semiconductors and graphitic nanomaterials. Nanofabrication is carried out either on campus or at BNL in the Center for Functional Nanomaterials. When structured into quantum dots, photonic crystals, or antidot lattices, these materials offer rich opportunities for fundamental research of light-matter interaction down to the ultimate quantum limit where control and manipulation of single electrons, excitons, or photons is possible. Device applications are in classical and quantum information processing such as quantum cryptography. To this end, the lab explores cavity-embedded SWCNTs for their utility in single photon sources. Another topic aims to realize scalable quantum photonic devices based on vertical QDs and photonic crystal nanocavities.
Collaborative activities with Prof. EH Yang's group from Stevens ME focus on CVD growth of graphene, strain-actuated graphene ribbons, and graphene antidot superlattices, promising applications in broadband light detection from VIS to FIR. Furthermore, the lab explores novel ways to fabricate plasmonic nanogap arrays with high throughput and at low cost based on interference lithography.
