Accessible High-Performance Double Nanohole Tweezers
Nanohole optical tweezers can be used without expensive top-down approaches such as electron microscopy or focused-ion beam milling by using polarization analysis to identify double nanoholes. Different substrates can also improve trapping and tape exfoliation can be used to simplify fabrication.

Isolating and enhancing single-photon emitters for 1550 nm quantum light sources using double nanohole optical tweezers
Plasmon-enhanced optical trapping was used to isolate nanocrystals with discrete levels of erbium ions. These levels were detected by observing discrete levels of emission from the erbium ions. Future work will investigate nanocrystals containing single erbium ions as single-photon sources.
