Enhancement of carbon nanotube photoluminescence by photonic crystal nanocavities

Abstract

Photonic crystal nanocavities are used to enhance photoluminescence from\nsingle-walled carbon nanotubes. Micelle-encapsulated nanotubes are deposited on\nnanocavities within Si photonic crystal slabs and confocal microscopy is used\nto characterize the devices. Photoluminescence spectra and images reveal\nnanotube emission coupled to nanocavity modes. The cavity modes can be tuned\nthroughout the emission wavelengths of carbon nanotubes, demonstrating the\nability to enhance photoluminescence from a variety of chiralities.\n
