Fig. 3From: InGaAsP/InP Nanocavity for Single-Photon Source at 1.55-μm Telecommunication BandVarying mode wavelength λ and Q factor as the a vertical and b lateral sizes deviate from the optimized conditions for both modes O and A. Note that the vertical sizes, i.e., the layer thicknesses, are tuned by λ B or ρ but displayed in terms of the spacer thickness t 0. The lateral sizes are tuned by cavity diameter D or air-aperture diameter d Back to article page
