We report on near infrared semiconductor nanopatch lasers with subwavelength-scale physical dimensions (0.019 cubic wavelengths) and effective mode volumes (0.0017 cubic wavelengths). We observe lasing in the two most fundamental optical modes which resemble oscillating electrical and magnetic dipoles. The ultra-small laser volume is achieved with the(More)
Plasmonic gold nanorods are widely used as sensors to detect the changes in refractive index of the surrounding medium. 1 The small detection volume around gold nanorods allows to study local attachment/detachment of proteins with high precision on single nanoparticle level. 2,3 The measurement of these dynamics requires a combination of high time(More)
