Subwavelength hybrid plasmonic nanodisk with high Q factor and Purcell factor
2011 (English)In: Journal of optics, ISSN 0150-536X, Vol. 13, no 7, 075001- p.Article in journal (Refereed) Published
Optical nanodisk resonators based on a hybrid plasmonic waveguiding geometry areinvestigated theoretically in the wavelength range of 1200–2000 nm with their radii varyingfrom 320 to 1000 nm. Due to the fact that a hybrid plasmonic structure can efficiently confinelight in a deep-subwavelength mode volume with a relatively low propagation loss, thenanodisks designed exhibit simultaneously a high Q factor and a high Purcell factor. For ahybrid plasmonic nanodisk with the radius of 1000 nm, a Q factor of 819 and a Purcell factor of1827 are achieved at the telecommunication wavelength of 1558 nm.
