Acquisition of Closed-Cycle Optical Cryostat to Investigate 1D and 2D Material Plasmonic Structures
Abstract
This DURIP project funded the acquisition of a closed-cycle optical cryostat that was installed in winter of 2018. Specifically, we purchased a Montana Instruments Cryostation that is cable of sample temperatures down to 3.5 K, with electrical feedthroughs and high NA optical access. The cryostat has been in constant use since its installation and continue to be used in the study novel 1D and 2D material (WSe2, graphene, boron nitride, carbon nanotube) structures for applications ranging from nonlinear plasmonic to single photon emitters for quantum information applications. The PI (Schaibley) is currently leading the project 'Plasmonic Amplification through On-Chip, Four-Wave Mixing in Hybrid 2D Material Plasmonic Structures,' funded by AFOSR-YIP 2017 (FA9550-17-1-0215). The PIs (Schaibley and LeRoy) also have a current AFOSR pilot project entitled: 'Towards Single Photon Transistors with 1D and 2D Materials' (FA9550-18-1-0049). Our research has applications to the development of novel optoelectronic and computing device technologies which is crucial to maintaining the technological, scientific, and cybersecurity superiority of the United States. The PI (Schaibley) is also engaged in a collaboration with Dr. Josh Hendrickson (AFRL) to investigate both 2D material plasmonic structures and single quantum emitters, and is writing a proposal to send a student intern to work at AFRL in 2020 through the NSF INTERN program. This DURIP has allowed for the construction of a dedicated optical setup that has greatly enhanced the productivity of our AFOSR research projects. Specific accomplishments include demonstration of a 2D semiconductor plasmonic modulator, and evidence of charging of moire excitons in bilayer heterostructures for deterministic integration with carbon nanotube plasmons.
