(a) Natural Rb Doppler broadened spectrum, as measured through the cell attached to the silicon chip. (b) Normalized measured spectrum (blue solid line) and calculated spectrum (green dashed line). Calculations were performed based on the actual dimensions of the ACWG and the density of the vapour.
