Enhancement of second-harmonic generation in micropillar resonator due to the engineered destructive interference

Abstract
We show, that engineering the cavity aspect ratio of AlGaAs micropillar resonator allows for the two order of magnitude increase in the efficiency of second harmonic generation at telecom wavelengths.
arXiv commentIn this version of the article, the error in determining the pump peak power has been corrected. The pump power was verified by integrating the Poyting vector over an area with a radius several times larger than the beam waist radius and it was determined that the peak power is 0.002 W instead of 0.008 W, which only affected the values of the nonlinear conversion coefficient shown in Fig. 3 (a-b)
