17. The intersubband splitting is minimal and equals the symmetric- antisymmetric gap when the QW is perfectly balanced (or symmetric). In that case the wave functions and corresponding subbands are delocalized in a sense they belong to both layers simultaneously. Here we consider the situation when the system is far away from its balance, so in fact each wave function is confined within corresponding layer. Therefore the terms subband and layer are equivalent throughout this discussion.
18. - 2, approximately the same value is extracted from the sum of optically measured concentrations in each subband.
