Abstract

In this letter, the authors observe high quality (Q up to 20 000) whispering gallery modes (WGMs) with small modal volumes V∼0.3 μ m3 in 4-5 μm Al (Ga) AsGaAs micropillars by employing an experimental geometry in which both excitation and collection of emission are in a direction normal to the sidewalls of the pillars. They show that WGMs provide at least two times larger values of the figure of merit for strong coupling applications QV compared to "photonic dot" states in pillars with comparable size.
